A.J. Jacobs Ted Talk

For a full year, A.J. Jacobs, the author of June's discussion book, Drop Dead Healthy, followed every piece of health advice he could - from applying sunscreen by the shot glass to wearing a bicycle helmet while shopping. Onstage at TEDMED, he shares the surprising things he learned.

Immersing himself in alternate lifestyles and long, hilarious experiments (usually with himself the guinea pig), writer A.J. Jacobs tests the limits of behavior, customs, culture, knowledge - and his wife's sense of humor.
