How does the body know when to switch? 5'-AMP is the signal. I believe it's the same metabolic system, whether we are talking about hibernation or not.

This is the first example of a gene that is turned on by darkness, where darkness itself is a signal. Twelve hours of darkness didn't do the job; it had to be at least 48 hours.

These animals dig deep burrows. They are constantly in the dark. Why not darkness as a switch?

When Lee and Jack win, it is good for golf. When I win, it is better.

When they made it 2-2, I just didn't have the sense that it would totally switch the other way even though they caught up.

I'm quite subdued, believe it or not. I switch it on for the camera.
