Hi, Ifnpman...I'm right there with you in your fears, and also your response to Roger Ebert. It's hard to watch him, knowing what a vital human being his has been and IS!
One thing I've thought of as I read your post is that you are young. I'm much older and am facing the prospect of being alone in my retirement years and the ensuing aging and infirmity. Yes, I have fears, from having witnessed both my parents with their lingering cancer and deaths. In dealing with this, I've come to the conclusion that dwelling on it while I am functional and relatively healthy, it is better to take each day as it comes... and be grateful for that good day. There are things I actually enjoy and look forward to doing, and I focus on those.

I'm very impressed by your educational background and your understanding of psychological issues. You are well ahead of the game in that respect, having insights into your own thoughts.

Patty
