Many happy returns Blast!
Echoing MoBOB sentiments, at 45, I am not even half the age of my still alive and kickin' 98 year-old grandmother. So don't get too down on this milestone bubba.

And while 50 may be the new 40, things do start "breakin'" at 40 no matter what shape you are in... my first indicator was the eyes! Reading glasses are a pain...
