Are you terrified of dying in unbearable pain or does losing your limbs to leprosy scare you?

A new video reveals the world's most frightening diseases - from bacteria causing he face to rot and and die to worms that burrow into the eyes leaving sufferers blind.

Since being uploaded to YouTube by the US-based channel They Will Kill You, the ten-minute film has been viewed almost seven million times.

Not for the squeamish, it shows an agonising condition that turns people's muscles into solid bone.

It also reveals a nasty bacteria found in contaminated shellfish that can trigger severe cramps and diarrhoea,evenutally causing the immune system to weaken.

Below, we reveal the most grisly conditions in the history of medicine...

1. NOMA (cancrum oris)

+13

A gruesome video reveals the top 10 scariest diseases in the world. One is Noma, or cancrum oris, a condition where bacteria gets into the body and causes the flesh of the face to become gangrenous and die

Scary: Noma, which usually occurs as a result of contaminated water or poor hygiene, kills 90 per cent of children who catch it

Ulcers form on the mouth, slowly eating away at the flesh until only yellowing teeth and jaw bone is visible.

This is not a scene from a horror film, but a condition called noma which still kills 90 per cent of impoverished children who catch it.

Mostly found in Asia and Africa, bacteria gets into the body as a result of poor hygiene or contaminated water, causing the flesh on face to become gangrenous and wither away.

The disease, also known as cancrum oris, is rapidly progressing and affects the genital areas as well as the mouth. 

Once, the condition was far more common, even in developed European countries and in the United States.

It was widespread among inmates and concentration camps during World War II due to the horrendous conditions.

Noma occurs when bacteria get into the body, generally a result of poor hygiene, contaminated water, lack of nutrition or diseases which cause the immune system to weaken.

While it has largely disappeared from industrialised areas, without treatment, noma kills 90 per cent of children who catch it. 

2. EMYCETOMA aka Madura’s foot

Gruesome: Emycetoma, Madura’s foot is a fungal infection causing hard swellings filled with pus to appear all over the feet, eventually stopping sufferers from using their limbs

This is a fungal infection capable of spreading all throughout the body but is typically found on the legs and feet.

Initially one suffering from this disease will notice a swelling on the foot, followed by a discharge of pus. 

The fungus then spreads, causing huge eruptions all over the appendage and serious damage to the surrounding tissue. Eventually this inhibits the use of the foot or leg.

Madura's foot is actually fairly painless which often leads to a late diagnosis. 

There are currently no vaccines to treat it but it can be avoided by keeping your hands and feet clean as well as emerging shoes while in fields and other natural areas.

Although it is endemic in Africa, India and the Central and South Americas, it has also been found in southern US states and in homeless people or those suffering HIV.

3. COMPLEX REGIONAL PAIN SYNDROME (CRPS)

Agony: Complex regional pain syndrome causes chronic and often debilitating pain in the body - and swelling too. It usually occurs after a serious injury

CRPS is a disease which causes people to suffer severe pain - sometimes continuing and debilitation - and often at just a stroke of the skin.

It occurs due to a breakdown of the nervous system and central nervous system. 

Studies also show that the pain and discomfort caused by CRPS can lead to mental health issues such as depression and anxiety.

Symptoms begin to show after serious injury involving tissue damage. While it usually begins in the hands it has the potential of spreading all over the body.

Someone suffering from CRPS will feel burning and stabbing pains or grinding and throbbing sensations.

It can also cause numbness, swelling joint pain and insomnia. 

This disease is treatable although the road to recovery is a long and complicated, involving physical therapy and sometimes surgery.

4. LEPROSY

Leprosy is a contagious infection that causes inflammation in the skin, eyes, nerves and respiratory tract.

It is contracted from exposure to a certain type of bacteria called Mycobacterium.

Symptoms can actually go unnoticed for years resulting in poor eyesight the loss of feeling in the limbs or infected area.

As people lose feeling in their limbs, wounds and infections occur and eventually they may lose parts of their body.  

Leprosy has been around for thousands of years and in the old days they used to quarantine anyone with leprosy into leper colonies so the disease would not spread. 

Contagious: Leprosy is a fast-spreading infection that causes scaly skin, loss of eyesight, and a loss of feeling in the part of the body that are affected

But modern science has proven that it's actually not all that contagious so taking such measures did little to stop it.

Leprosy is often referenced in the Bible although scholars believe any biblical reference to the word likely refers to not just leprosy as we know it today and also a wide array of diseases involving scaly skin. 

Over the centuries there have been many methods of treating leprosy including blood sacrifices of children or virgins and rituals involving snakes.

Today, multi drug treatment is available to rid victims of their sickness.

5. FILARIAL WORM AKA LOA LOA WORM

Filarial worm is a parasite that has the ability to live in people's eyes.

It effects over 200 million people and is the second leading cause of blindness worldwide.

Filarial worms are not contained just in the eyeballs and when they occur elsewhere in the body they cause a condition called elephantiasis, which results in the lower extremities swelling up larger than normal. 

Other potential symptoms include a rash, intense abdominal pain, arthritis and papules.

Curing filarial worm infections depends on exactly what type of filariasis one has, and is often treated with antibiotics.

Stomach-churning: Filarial worm, also known as the Loa Loa worm, is a parasite that has the ability to live in people's eyes, and is the second leading cause of blindness worldwide

6. VIBRIO VULNIFICUS

This is an extremely virulent bacteria that can cause a severe infection.

It is contracted through eating raw shellfish and swimming with an open wound, as well as stings from stingrays.

This disease comes with many symptoms including vomiting, intense diarrhoea, blistering dermatitis and severe abdominal pain.

To make matters worse vibrio vulnificus weakens the immune system, affecting both the liver and bloodstream and ultimately killing those who do not seek proper treatment.

The origins of vibrio vulnificus only date back to 1979. 

Scientists believe this is because of the general increase in temperature and a decrease in the salt levels on the coast leading to an increase in the pathogen. 

While it is most commonly contracted from you eating contaminated and raw shellfish, 2005 saw a massive increase in cases among the Hurricane Katrina victims in New Orleans who were surrounded by contaminated flood waters.

Horrific: Vibrio vulnificus is an extremely virulent bacteria that can cause vomiting, intense diarrhoea, blistering dermatitis and severe abdominal pain. It is usually caught through eating contaminated shellfish

7. PICA

Pica is a disorder that causes people to inexplicably gain an appetite for non-food items.

This can range from anything from paper and wood to faeces or urine. 

This does not include people with mental disabilities or anyone who eats non nutritious items for cultural or religious reasons, making it difficult to diagnose since it can potentially be caused by another unrelated disorder.

Problems from Pica can be quite severe, faeces and dirt cause health hazards. 

Additionally, someone with Pica might ingest something toxic such as paint or lead which can ultimately lead to poisoning. 

Frightening: Pica is a disorder that causes people to inexplicably gain an appetite for non-food items, which can range from anything from paper and wood to faeces or urine

In St Joseph, Missouri, a man was found with more than 1,400 items in his stomach.

Historically, Pica dates back to the 13th Century where it was referenced in Greek and Roman literature. 

By the 16th century instances of this disorder began appearing in medical texts and it is still unknown how many of those instances were actually behaviours resulting from Pica or were signs of another disease altogether. 

Pica comes from the Latin name for the magpie, a bird which is known for to be indiscriminate about what it eats.

In St Joseph, Missouri, a man was found with more than 1,400 items in his stomach due to Pica disorder

8. FIBRODYSPLASICA OSSIFICANS PROGRESSIVA (FOP)

With fewer than 800 cases worldwide, FOP is a very rare disease in nearly impossible to treat. 

FOP causes the body's tissue repair systems to stop working and it begins to heal damaged muscles, tendons and tissues by turning them into bone.

The new bones do not have flexible joints so once they start to grow throughout the body it becomes nearly impossible for someone with FOP to move.

Painful: Fibrodysplasia ossificans progressiva (FOP) is a disorder in which muscle tissue and connective tissue such as tendons and ligaments are gradually replaced by bone

Cutting off the the newly formed bones makes the problem even worse as this causes the bone growth to run even more amok.

Any knock to the body causes more bones to being growing, thus causing a faster deterioration of the body.

In the most extreme instance, a man named Harry Eastlake managed to live up to age 40 with FOP but by the end was completely immobile aside from his lips.

Mr Eastlake donated his body to science soon before his death and his skeleton remains at the famous Mutter Museum in Philadelphia, Pennsylvania.

9. CLARKSON’S DISEASE (SYSTEMIC CAPILLARY LEAK SYNDROME – SCLS)

SCLS is a condition in which one's blood vessels begin leaking plasma. 

The plasma is then absorbed by the skin with nowhere to go - causing the person to start bloating like a balloon.

Rare: Systemic capillary leak syndrome (SCLS) occurs when blood vessels start leaking, causing the person to bloat like a balloon. This can damage vital organs and tissues, ultimately causing death

Although rare, the only way to treat Clarkson's disease is to to inject fluids into the body to counter the bloating.

This is a problem in itself since it takes three full days for the bloating to stop - and in the mean time it can lead to damage to vital organs and tissues ultimately causing death.

SCLS gets its name from Dr Bayard Clarkson, who first diagnosed the disease in 1960 in a patient who was experiencing spontaneous bloating. 

Since then about 150 people have been diagnosed with Clarkson's disease. The cause is still unknown despite research.

10. ELEPHANT MAN SYNDROME

Joseph Merrick was born in Leicester, England in 1862. 

Joseph was born as a healthy baby but as he grew older show signs of use five is developing lumpy skin with the similar colour and texture to that of an elephant and so he was nicknamed the ‘Elephant Man’. 

His right arm and hand grew to a disproportionate size to that of his left and both his feet swelled up to enormous sizes.

The skin on his face also appeared to be lumpy. To this day medics are baffled as to the cause of Merrick’s condition.

Mystery: Joseph Merrick was born in 1862 England and was known as the Elephant Man. It is believed he may have suffered from a combination of disease including Proteus syndrome, which causes tumours to form all over the body

Although there is no consensus there have been a few theories submitted.  Merrick himself believed as did many people of his time that his condition was a result of a maternal impression. 

This theory states that a deep emotional trauma or feeling experience by pregnant mother will have an effect on her unborn child's development.

Apparently Merrick’s mother had been frightened and knocked down by elephants at the fair and as a result she gave birth to what has become known as the ‘Elephant Man’.

Others believe he may have had Proteus syndrome. 

This a condition in which overgrowth and abnormal bone development caused tumours to grow all over the body.

Most experts think it was a combination of Proteus syndrome and other conditions such as microcephaly (a condition which causes abnormally small heads), hypertosis (excessive growth of bone) and neurofibromatosis (a condition where tumours form all over the body). 

Despite all these theories, the exact cause of Joseph Merrick’s deformities remains shrouded in mystery. 

Where luxury cars go to die: Inside the overgrown 'tyrant's car park' where Bentleys and Mercedes totalling millions have been abandoned by their rich owners

• The car park in Chengdu, China, is home for at least two Bentleys, two Land Rovers and three Mercedes Benz
• There's over 200 vehicles in various conditions that have been abandoned by their owners for different reasons
• Officials are struggling to decide what to do with the vehicles and weeds and bushes grow around the cars 

These startling images show an overgrown car park, where cars totalling millions have been left abandoned and taken over by weeds.

Inside this small lot in Chengdu, China, there are at least two Bentleys, two Land Rovers, three Mercedes Benz and even the odd motorbike according to People's Daily Online.

They all have one thing in common - they've been abandoned by their owners. 

Where luxury motors go to die: One of the Bentleys currently parked in the car park in Chengdu, which has been dubbed 'tyrant's car park'

Abandoned: The vehicles have been abandoned by their owners, often over a space of years. Many were swallowed by the plants

Gone: Dust has gathered on the surface as well as inside while vines and weeds have sprung up all around the vehicles (pictured) 

There are over 200 vehicles, dubbed 'zombie cars', in the lot.

The place they're kept in is called a 'tyrant's car park' because of the value contained in the storage space.

Some of the cars have been kept in the same place for more than two years as bushes and trees grow up around them, shielding them from the outside world.

The two Bentleys, one a Bentley Continental GT and another Bentley Flying Spur, are worth at least 3 million Yuan (£300,000) each in China.

Then there's the Audi, Land Rover and Mercedes Benz. 

Majority of the vehicles are involved in ongoing criminal case either directly or indirectly, which means they can't be claimed by their owners.

Others have been abandoned as they were ready to be scrapped or their owners lacked the correct paperwork. 

The cars have become a headache for the local authorities, who struggle to decide what to do with them.

While some have been cleared for auctions, others continue to arrive and be stacked up in the graveyard of cars. 

Huge: There are over 200 vehicles, dubbed 'zombie cars', in the lot, including several luxury cars. Their total worth is in the millions

Controversial: Majority of the vehicles are involved in ongoing criminal case, which means they can't be claimed by their owners

Bureaucracy: Others have been abandoned as they were ready to be scrapped or their owners lacked the correct paperwork

Back to nature: Some of the cars have been kept in the same place for more than two years as bushes and trees grow up around them, shielding them from the outside world 

Struggling: The cars have become a headache for local authorities, who struggle to decide what to do with them as they grow in numbers

Manchester United paid Jose Mourinho £4m to stay away from rivals as former Chelsea boss prepares to sign £75m five-year deal

• Manchester United paid Jose Mourinho £4million to stop him joining rivals
• Former Chelsea boss will be on £75m five-year deal with £200m to spend
• Mourinho refused to accept a 'behavioural clause' in big-money deal
• An agreement with Mourinho was reached midway through the season
• Louis van Gaal was told of his sacking by his wife Truus after FA Cup win

Jose Mourinho was paid a staggering £4million by Manchester United not to take a job elsewhere while they decided the future of Louis van Gaal.

An agreement was reached midway through the season to give United the option of bringing him in if Van Gaal failed to meet their targets.

Sportsmail can also reveal that Mourinho refused to accept a 'behavioural clause' in his five-year, £75m deal despite concerns among the United hierarchy over his eccentric touchline behaviour. 

Jose Mourinho has been on the Manchester United payroll for months, and will be given £200m to spend

Louis van Gaal (centre right) will be sacked by Manchester United and replaced by former colleague Mourinho

The 53-year-old was fined £229,900 and received two stadium bans during his two spells at Chelsea and United are desperate to avoid the negative publicity those incidents generated.

However, Mourinho refused to agree during negotiations in January, highlighting his strong bargaining position as United's season unravelled. Unlike Manchester City's pre-contract deal with Pep Guardiola, the unique arrangement with Mourinho was merely to ensure he would be available if required. 

Had Van Gaal been deemed to have been a success, by whatever criteria United laid down, he would have stayed for the last year of his contract. The deal was first reported by Spanish newspaper El Pais in March.

As it is, former Chelsea manager Mourinho will have £200m to spend on new players as United, who lifted the FA Cup on Saturday, plot a route back to the top of the English game after missing out on a top-four spot for the second time in three seasons.

United hope to have their transfer business completed by the end of Euro 2016 to ensure their manager has his squad in place when they return to training.

The club wanted to keep the agreement with Mourinho secret from Van Gaal, who was his boss at Barcelona, but by Sunday afternoon the United hierarchy were left embarrassed by another PR own goal.

JOSE'S CAREER SO FAR

2000: Benfica

2001–2002: Uniao de Leiria

2002–2004: Porto

2004–2007: Chelsea

2008–2010: Inter Milan

2010–2013: Real Madrid

2013–2015: Chelsea

2016 onwards: Manchester United?

The fact Van Gaal knew he had lost his job within minutes of winning the FA Cup is considered by senior figures as more shameful than the departure of David Moyes, who learned of his own dismissal from media reports before executive vice-chairman Ed Woodward had the opportunity to inform him personally.

At Wembley on Saturday it was Van Gaal's wife Truus who told him she had seen the story on the BBC website shortly before he was due to give his post-match press conference. 

Mrs Van Gaal was said to be extremely upset, which would explain the tetchy nature of the exchanges her husband then had with the media. He is also understood to be furious with his Old Trafford employers.

News of Mourinho's appointment, which is expected to be confirmed on Tuesday, was not leaked by United. But Woodward will face questions about how Van Gaal's moment of triumph was marred by such public humiliation.

Van Gaal was involved in some tetchy exchanges with the media after being told of his dismissal by his wife

Once again the pressure will be on Woodward to appoint a more experienced director of football to handle football matters while he retains control of off-the-field business.

Van Gaal had a meal with his coaching staff on Saturday night and will now prepare to leave Manchester, with a future role at the club considered extremely unlikely given his anger at the situation.

The Dutchman and his wife had immersed themselves in life in Manchester. They were regulars at restaurants in the Cheshire village of Hale, while Truus had become an active member of local sports clubs.

The future of assistant Ryan Giggs (left) is unclear; he is keen to stay and work alongside Mourinho at United

Under Van Gaal, Manchester United have disappointed and it is hoped Mourinho will take them back to the top

On Sunday night the future of Ryan Giggs was still unclear. He will be disappointed not to have succeeded Van Gaal but club insiders believe he wants to stay at United and hope the prospect of working with Mourinho will keep him at Old Trafford. 

The players would like Giggs to stay, given the central role he plays. When they have 11 v 11 practice two days before a game it is Giggs who organises the opposing team to mirror the side United will face. He also works directly with the players on set-pieces.

Woodward, it is understood, met Mourinho in London on Sunday with a view to confirming the appointment on Tuesday.

By Sunday sources were providing some insight into why it was felt United had to make a change, and not just because of their failure to qualify for next season's Champions League. 

The relationship between Van Gaal and his players had become fractured, with senior players exasperated as much with his failure to control the younger professionals as they were with some of his methods.

Requests not to post their personal videos of the Upton Park bus attack on social media were ignored, while there was a suspicion among some members of the dressing room that players were pulling out of games simply because 'they didn't fancy it', only to train the next day.

Van Gaal's insistence on playing a more regimented style of football became a problem for some of the flair players, with one senior pro telling the Dutchman he intended to play his natural game because following orders would result in him being dropped again.

David de Gea, as revealed last week, would have asked to leave Old Trafford had Van Gaal been allowed to remain in charge for a third season.

It is understood David de Gea (centre left) would have asked to leave if Van Gaal stayed for another season

Van Gaal (right) is understood to have lost the respect of the players, and Mourinho will shake things up

Some of the players would certainly like Mourinho to shake things up a little. Stories of younger professionals asking catering staff to boil them an egg to take home is one measure of how soft the environment has become since Sir Alex Ferguson retired in 2013.

The players would also like Mourinho to challenge Woodward over commercial demands. After they suffered that crushing 3-2 defeat at West Ham at the end of the season, the players had to report to Old Trafford the next morning to drive miniature Chevrolets around the car park.

Mourinho has already identified the players he wants to sign ahead of his arrival, with 23-year-old Sporting Lisbon midfielder Joao Mario one of his principal targets.

Chelsea close in on £60m-a-year kit deal with Nike after ending adidas partnership six years early

• Chelsea's current kit partnership with adidas will end after next season
• The Blues will earn double the amount per annum with adidas' rivals Nike
• Nike deal will be worth £60million, while adidas currently pay £30m 

Chelsea are set to sign a kit sponsorship contract with Nike worth £60million-per-year in what will be the second biggest deal in the Premier League.

The Blues announced earlier this month that they are parting company with adidas at the end of next season, after the pair decided to terminate their current deal six years early.

Adidas' shirt deal was worth £30million annually - a figure that will be doubled by their American sportswear rivals, despite the fact Chelsea won't be competing in Europe next season.

Chelsea are set to agree a £60million-per-year kit deal with Nike which will begin at the 2017-18 season

TOP PREMIER LEAGUE KIT DEALS

1) Manchester United - adidas (£75m-a-year)

2) *Chelsea - Nike (£60m-a-year)

3) Arsenal - Puma (£30m-a-year)

4) Chelsea - adidas (£30m-a-year)

5) Liverpool - New Balance (£25m-a-year)

6) Manchester City - Nike (£12m-a-year)

*Chelsea's Nike deal will come into effect from the start of the 2017-18 season.

As revealed by Sportsmail, Chelsea and adidas' split is said to be by mutual consent but talks were instigated by the former for some time.

The west London outfit had grown increasingly annoyed by the way German company have been concentrating on Manchester United, Real Madrid, Bayern Munich and Juventus, and on signing new players.

And the financial gain of Nike's deal will increase Chelsea's leeway in regards to Financial Fair Play too.

UEFA's monetary model is calculated over a three-year period with clubs currently allowed to spend around £23m more than they earn for the 2015-16, 2016-17 and 2017-18 seasons.

Chelsea's failure to qualify for the Champions League will cost upwards of £40m, a figure that won't hinder them severely now with the incoming Nike deal as well as the imminent extra revenue that will be sustained from the Premier League's bumper TV deal.

Chelsea's new deal with Nike will be significantly more per year than the latter's with Manchester City (£12m) and Arsenal's agreement with Puma (£30m).

However, it is still below Manchester United's staggering 10-year £75m-per-season contract with adidas, which came into effect this term.

Manchester United boast the biggest lucrative shirt deal in England - earning £75m-a-year from adidas

Chelsea's London rivals Arsenal earn £30m-a-year from German sportswear company Puma

Manchester City are currently sponsored by Nike but earn a fifth's of Chelsea's likely deal - at £12m-a-year

Inside the $16.7bn fortune of Steve Jobs' widow - including her two private jets, her $138million yacht and $12.7bn Disney share

• Laurene Powell Jobs, 52, is the sixth richest woman in the world
• She has controlled Steve Jobs' trust since his death in  October 2011
• Her assets include a 7.8 per cent share of The Walt Disney Company
• Jobs also inherited her husband's $560 million stake at Apple
• She owns four homes and a 260-foot yacht co-designed by her husband 

When Steve Jobs passed away in October 2011, most of his assets passed on to his wife, making her one of the 50 richest people in the world.

Laurene Powell Jobs, 52, married the tech mogul in 1991 - ten years before the release of the first iPod - and now manages a $16.7bn fortune according to Forbes.

She owns, among other things, two private jets, four real estate properties and shares of the Walt Disney Company and Apple, Business Insider reported.

Powell Jobs is now the sixth richest woman in the world based on Forbes' ranking, behind French L'Oreal shareholder Liliane Bettencourt, Wal-Mart heiress Alice Walton, Mars heiress Jacqueline Mars, Italian Michele Ferrero's widow Maria Franca Fissolo and German BMW heiress Susanne Klatten.

Laurene Powell Jobs (pictured with Steve Jobs in 2010) married the tech mogul in 1991 - ten years before the release of the first iPod - and now manages a $16.7bn fortune

Her fortune comes mainly from the Walt Disney Company she inherited from her husband, according to Business Insider.

That share was worth $7.4 billion when he sold Pixar, his animation studio, to Disney in 2006. It has now increased to $12.7 billion, Business Insider reported.

The Laurene Powell Jobs Trust, which Jobs has managed since the death of her husband, is the largest individual shareholder at the Walt Disney Company, with a 7.8 per cent stake according to Forbes.

Powell Jobs' share of Apple, on the other hand, is tiny compared to what it could have been: according to Business Insider, her stake at the company comes to $560 million.

That's not even one per cent of the $65 billion his original 11 per cent stake at the company would represent today, the website wrote.

But he sold it when Apple ousted him in 1985.

Steve Jobs never got to see the 26-foot, $138 million yacht (pictured) that he imagined with French designer Philippe Starck. He died before the finished yacht, named Venus, was unveiled in October 2012

Among four real estate properties in total, Powell Jobs owns the Palo Alto house (pictured) where she lived with her husband and their children, worth $8 million

Her assets also include four real estate properties, Business Insider reported. One of them is the house where she lived with her husband and their children, located in Palo Alto and worth $8 million.

She owns two additional properties in Woodside, each worth $7.5 and $10 million, the website wrote.

Powell-Jobs purchased the last one, a three-acre property in Malibu, in March last year for $44 million according to Wealth-X.

Powell Jobs pledged $50 million to a national high school reform project in September last year

She has also inherited the 26-foot, $138 million yacht her husband imagined with French designer Philippe Starck.

He died before he could see the finished yacht, named Venus, which was unveiled in October 2012.

His family gave iPod shuffles with the name of the ship written on the back as a thank-you to everyone involved in the construction, Wealth-X wrote.

Powell-Jobs also owns two private jets - a 2013 Gulfstream G650, currently priced at $58,8 million, and a 1999 Gulfstream G-V, now worth $9.95 million.

The rest of her fortune is divided between cash and liquid assets according to Business Insider, and comes from stock transactions, dividends and investments, as well as previous salaries and bonuses.

Powell-Jobs, who met her husband in 1989 when he came to give a lecture at Stanford Business School, where she was a student, had three children with him.

She has co-founded several programs to assist disadvantaged students.

The latest, XQ: The Super School Project, is a national campaign to reform high schools.

She pledged $50 million to the project in September last year.

Powell Jobs is one of the top donors to the Ready for Hillary Super PAC according to Forbes and supports the DREAM Act, a bill that would establish a path to US citizenship for children of undocumented immigrants.

She also owns two private jets, one of which is a 1999 Gulfstream G-V (file picture), now worth $9.95 million. Powell Jobs also has shares at The Walt Disney Company and Apple

The other private jet, a 2013 Gulfstream G650 (file picture), is currently priced at $58,8 million. The rest of her wealth is divided between cash and liquid assets

The major part of Powell Jobs' fortune comes from a 7.8 per cent share of The Walt Disney Company, which is now worth $12.7 billion
