Hey MH last night I watch a bit of a show on the discovery channel that showed a 16 year old boy in Nepal who fasted for 10months with no water......they called him Buddha Boy.
I don't know how true the 10months part is but discovery channel did film him for I think 5 days straight while he meditated with no water, no food, no movement. They also showed he was able to maintain his body temperature with no clothes on during the 5 nights where the temp was 3 degrees(think thats about 30F). He had sweat coming from his neck and body wearing nothing while the whole film crew were freezing with big jackets on.
Just goes to show the power of the human mind. Pretty amazing stuff, if even part true.
