STEALING TIME: THE NEW SCIENCE OF AGING
Wednesday at 8 on PBS
We live during a time of discovery so revolutionary that we may be able eventually to double or even triple our record 76.5-year life span, believes executive producer John Rubin. Through reports and interviews, this three-hour program contends that the forces that control aging will soon be in our hands.
The first hour explores the natural history of aging; the second explains the aging process and asks what can be done about it; the third looks at the aging brain and disputes the idea that brain cells begin dying after a certain age.
CAPTION: Two "Star Trek" stalwarts: Armin Shimerman, above, as the crafty Quark, and Michael Dorn as Lt. Cdr. Worf.
