Looking at those around me, I see that age is really just a number. You are only as old as you feel. Right now, I'm feeling down right decrepit.
I have two young friends, sisters both in their 40's, each with serious health issues. They carry on as best they can, but over the past couple of months their families and I can't help but worry about them. I have other friends with various ailments, not quite so serious, but still bad enough to disrupt their lives, and they also do the best they can to carry on. What else can you do, after all?
