The current state of science around “youthenizing” people 
This public frenzy has unlocked a flood of investment from venture capitalists—funding for longevity startups is up by 75% over the past year, according to CB Insights—and pharmaceutical companies. The opportunity for them, if they can create new drugs or pioneer techniques to slow or reverse aging, is potentially colossal. “Every single person on the planet is aging,” says Dr. Mehmood Khan, CEO of the aging philanthropy Hevolution, which is based in Saudi Arabia (one of the largest funders of aging research in the world). “This affects every organism. It’s personal.”
But longevity scientists working today temper this enthusiasm with a sobering reality. Their focus is not on immortality, or even adding a few more years to people’s lives. It’s ensuring that they spend those final years in as healthy a condition as possible.
They are in the business of increasing health span, not lifespan. “We are not focused on trying to work on longevity,” says Kirkland, director of the Center for Advanced Gerotherapeutics at Cedars-Sinai. But it could be a welcome side effect. “Hopefully we live to 100 or something like that, completely functional, and just not wake up one morning.” The goal is to extend the number of years (however many they may end up being) during which people can live independently, actively, and without being encumbered by serious disease.
“Everybody recognizes that at this point of increasing prosperity and increasing life expectancy all around the world, the burden of caring for older adults suffering from chronic diseases has emerged as one of the most pressing global challenges of our times,” says Dr. Shalender Bhasin, professor of medicine at Harvard University and director of the Claude D. Pepper Older Americans Independence Center at Brigham and Women’s Hospital.
