Yes - I think that's a big part of it. A friend's husband had diabetes-related kidney failure. It was a stellar day when his and his new kidney could drive again - without her!

I'm not sure its entirely male, though - with my recent adventures in auto-immune world, my pleas for him to drive slower in the snow increase when my inflamation/anxiety level is up! My reumatologist decided yesterday that my current diagnosis is RA, not Lupus AND RA, so that's a good thing. We will see what my inflamatory markers look like when the blood work comes back.

Kathy -
not sure when/if another PET will be scheduled. He has an RO appointment next week, and an ENT visit in on Valentine's day. Will update when there is something to update.
