This has been an unbelievable ride.

The main purpose is to exploit you. Well, it's a great honor to be exploited.

I was nervous as hell all day.

Usually when you work with mice you can pet them. But any mouse on a restricted diet would try to jump out of the cage and bite you.

If you restrict their intake by 20 percent, they live even longer, and restrict them to 50 percent, they live longer still. But restrict their intake by 60 percent and they starve to death.
