The elixir of immortality has yet to be discovered, but for now we have some of the oldest men and women in the world revealing their secrets to staying healthy longer.
A man from Devon, England recently celebrated his 103rd birthday, and also revealed his secret for living a long and healthy life.
The world's oldest man, Francisco Nunez Olivera from Spain, recently celebrated his 113th birthday a few days ago, and shared his two secrets for longevity.
He said he owes his life to a diet of home-grown vegetables and a daily glass of red wine.
"I know I'm old but I don't feel old," Olivera said.
Frederick Vinecombe, the man who was born the same year World War One broke out, said there's also two things that have kept him alive all these years, but they're much more surprising than Olivera's.
His daughter said Vincecombe is not on any medication, has all of his own teeth and has never gone to a hospital for a illness.
So what's his secret?
