I went through a book-writing phase... I think it's over :)
After a while, after a certain age (I'm at that age), you just kind of take it in stride. Make the accommodations necessary, keep a trustworthy doctor in reserve, and enjoy life. I wrote that book when I was in a different frame of mind. Had to get it out of my system. Also thought I could help a few people. I think I did.
You're right to take matters in your own hands. We can't choose our genes, but we sure can choose the way we live.
I read you blog... I will be commenting, you know :)
