I've watched people push thier pulse down to the point that machines can loose it while they are meditating, and breath about twice a minute. But I've never heard of it for three weeks- I want to know if he was immersed in supercold water when he landed, and if he studies some of the more mentally oriented martial arts.

I also want to check his credit card and bank records. If this is true, I am curious to see if we can figure out how, but if it isn't, the money flow will show something. I also wonder if they checked for head trauma, he could be amnesic, but again, for three weeks it is a long time and it doesn't fit with the description of the state he was found in.
