David Blaine irritates me. I found his feats more about quests for egotistical attention than for actual entertainment value.

However, I now have respect this nut case because he has a strong respect for using science and also giving back to it.

In his talk, in which explains how he held his breath for 17 minutes, he tells how he essentially donated himself to science immediately after the event so doctors and scientists could study the effects of this kind of depravation on the human body.

Kudos, I say.
