Hey Bud, a friend of the DH and me also had both hips and knees done and has
been kicking herself for not doing it sooner!  She loves to dive and as long
as she could do that she put it off.  Once getting into a dive suit became
too hard, she gave in and had the joint replacements.  Now, when they travel
to exotic locales to dive, she can actually enjoy wandering around on land
for a day or two as well!  Go for it, everyone I know who has done says it's
ultimately worth it.

and it's faster than a whole body transplant  ;-)
and, no doubt, more effective than my frequent threats to my thumbs to take
the meat cleaver to them  (thumbs don't scare easily, I'm discovering)
