Director Mark Wexler embarks on a worldwide trek to investigate just what it means to grow old and what it could mean to really live forever. But whose advice should he take? Does 94-year-old exercise guru Jack LaLanne have all the answers, or does Buster, a 103-year-old chain-smoking, beer-drinking marathoner? What about futurist Ray Kurzweil, a laughter yoga expert, or an elder porn star? Wexler explores the viewpoints of delightfully unusual characters alongside those of health, fitness and life extension experts in this engaging new documentary, which challenges our notions of youth and aging with comic poignancy. Begun as a study in life-extension, How To Live Forever evolves into a thoughtprovoking examination of what truly gives life meaning. --(c) Variance
