6 Billionaires Who Want to Live Forever

The Ellison Medical Foundation, which, according to its website "supports basic biomedical research on aging relevant to understanding lifespan development processes and age-related diseases and disabilities," has donated about $430 million in grants to medical researchers since 1997, about 80% of which has been focused on antiaging developments.

"Death has never made any sense to me. How can a person be there and then just vanish, just not be there?" Ellison told his biographer Mike Wilson in 2003.

Since its launch, Calico has also entered into several partnerships with different organizations to help it cure aging.

Most recently, Calico announced in April that it was teaming up with the Buck Institute for Research on Aging, one of the largest independent, antiaging research organizations.

In 2013, the group garnered some attention for using genetic mutations to increase the lifespan of earthworms to the human equivalent of 400 to 500 years.

The 41-year-old has taken a particular interest in curing Parkinson's disease. Brin disclosed in 2008 that he carried a gene that puts him at higher risk of developing the disease. He has donated more than $150 million to find a cure for the disease.

For Brin, big data could hold the key to better understanding DNA and preventing neurodegenerative diseases like Parkinson's.

Brin, now president of Google's parent company, Alphabet, also pushed for medical research while he headed up Google X, the company’s semisecret moonshot lab.

One of the division borne out of that lab was the Life Science team, which focused on developing things like a glucose-detecting contact lens.

In August, Brin announced that the Life Sciences team would now be its own company under Alphabet and continue to work on "new technologies from early stage R&D to clinical testing — and, hopefully — transform the way we detect, prevent, and manage disease."

Last year, Andrew Conrad, head of the new Life Sciences division, said that the team was also working on a treatment that would embed nanoparticles in your bloodstream to detect for diseases like cancer.

"I'm most interested in questions about people. What will enable us to live forever? How do we cure all diseases? How does the brain work? How does learning work and how we can empower humans to learn a million times more?" Zuckerberg replied.

Zuckerberg and his wife, Priscilla Chan, along with Brin and his ex-wife Anne Wojcicki, are also founders of the Breakthrough Prize, which awards $3 million to scientists who discover new ways to extend human life.

According to a report from The Washington Post, Parker suffers from life-threatening food allergies and has relatives that suffer from autoimmune disorders.

The 34-year-old billionaire has donated millions to searching for a cure for allergies and for cancer research, according to the report.
