I don't feel I have the right to read this, much less comment. But as someone similar in age, I'm fighting my own fears of getting older, of having decisions I've made finally catch up to me, and that slow descent into becoming someone else I didn't want to be. I'm equally fearful of seeing the same thing happen to my wife.

In the end, all you have is your strength and your humor (and your salt), even if the rest is taken from you.

I wish you all the best as you walk along the ledge that is life.
