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).
