Man 'hibernated' for 24 days after fall

A man who slipped down a Japanese mountain survived unconscious in cold weather without food and water for more than three weeks by lapsing into a state of "hibernation", doctors said.

Mitsutaka Uchikoshi had almost no pulse, his organs had all but shut down and his body temperature had dipped by a third when he was discovered by a climber on Rokko mountain near Kobe, 24 days after he disappeared.
