"New research from Rockefeller University, performed in collaboration
with scientists at Duke University in North Carolina, reveals for the
first time that this extreme variability in people's perception of
androstenone is due in large part to genetic variations in a single
odorant receptor called OR7D4. The research is reported September 16
as an advance online publication of the journal Nature".

WOW!  That explains a lot. It almost makes me lose my cookies.
To be honest, I often could not stand the smell of myself on "T."
How is that for irony?
