David Blaine was one of the guest speakers at last year's TedMed. Thanks to TedTalks, his complete presentation "How I Held My Breath For 17 Minutes" is now online in its entirety.
In this highly personal talk from TEDMED, magician and stuntman David Blaine describes what it took to hold his breath underwater for 17 minutes -- a world record (only one minute shorter than this entire talk!) -- and what his often death-defying work means to him. Warning: do NOT try this at home.
