How to Live Forever (2009) on Netflix

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 a chain-smoking, beer-drinking centenarian marathoner have all the answers? What about an elder porn star? Wexler contrasts these unusual characters with the insights of health, fitness and life-extension experts in his 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 thought-provoking examination of what truly gives life meaning.
