	Does large breast size really mean that you have a greater number of
cells?  If you do weight training, your muscles will grow because each cell
gets bigger, not because more cells are produced.

	Apparently every mammal except humans lives for 1 billion
heartbeats.  Humans live for 3 billion, so our cells have to cope with more
metabolically-induced damage?
