On TV

By EMILY MITCHELL

One of humans' oldest dreams is to stay young. While the Fountain of Youth remains undiscovered, a PBS series, Stealing Time: The New Science of Aging, documents findings about genes, diet and exercise that hold the promise of buoyant longevity. The 3-hr. program, which airs in its entirety June 2 over most public stations and is available on videotape, explores revolutionary research that could lead to not only longer and but also healthier and more intellectually acute lives.
