Also, I remember hearing on the news a while back that well-done meat is more likely to cause cancer. I guess this is because of carcinogenic burnt stuff that's more common in well done meat.

Interpret this as you will-- it probably isn't related, but my father always ordered meat well done... and he died of stomach cancer when he was 48.

I don't let it bother me, though. I'll die before I order meat that's anything other than well done.
