Myles and Dave,
LOL!!!
Interesting ways to look at aging! I have realized I have outlived one grandfather by 4 years, and by 65 would pass my other grandfather and a grandmother, but don't think much of it. My main thought was to see our daughters marry and get on their own. Marked that off two months ago. I would like to retire and be able to share my trains with grandchildren, but if I don't see that, oh well.
Interesting on the shoulder. As ong as you can use it and it doesn't hurt, that's great!!
