How many cells in a human?

	A gram of cells grown in culture contains something on the order of 
1.0E9 cells. Therefore 70 kg of cells (=1 human) would contain something 
like 7.0E13 cells.  However there are a lot (=/- quite a few) of red blood 
cells which are considerably smaller than average, so this number may be low.

just to be pedantic but red blood corpuscles shouldn't count because they are
corpuscles and not cells (no nucleus).
