Been listening to Whaddayaknow on Public Radio, have you?  Heard the
same question today.

Actually the blood pressure wouldn't need to be that high to force blood
up to the legs that short a distance.  Just think how much further your
head is from your heart than a bat's legs are from its heart, or, for
that matter, a giraffe's head from its heart.  Now there's a real
plumbing problem; enough pressure to supply the head when reaching into
the treetops and not so much that it blows out blood vessels and cause a
stroke when it gets a drink.
