That description describes some people I know ..... In the middle of the day <img src="/images/graemlins/smile.gif" alt="" /> ... any day

Seriously I am not surprised even though I didnt see the program. I have seen another show do something similar.

When I was a kid we lived in a place that used to get cold every night, not freezing but close. We didn't have much heating, and I was able to teach myself not to shiver.
I used to be able to put myself into a very relaxed state, and push past the goose bumps and shivering by lowering my body temp. Then I was able to get a good sleep. If I went to sleep while shivering I felt like I needed more sleep.
These days I have lost that ability.
I guess that was similar to stabilizing his temp on the porgram.
