How to Live Forever, written by director Mark Wexler and Robert DeMaio, is a documentary that follows Mark on a three-year pilgrimage to discover the best practices and philosophies to help mitigate "the uncool trappings of old age." With the death of his mother (artist Marian Witt-Wexler) and the arrival of an AARP card, Wexler begins to wonder if one can truly achieve immortality.
