Dr. Thomas Perls has for decades studied so-called super agers, people who live deep into their 90s and beyond, essentially unburdened by the typical diseases of old age. He is convinced that the secret to this remarkable longevity is buried in people’s genes and passed down through generations.
But which genes harbor this power? And if researchers pinpoint the right genes amid thousands in a person’s body, could that knowledge be harnessed to develop drugs that mimic those genes and allow more people to enjoy longer, healthier lives?
