TripleR,
Thanks for the post.
Sometimes it takes reading something like what you wrote to remember just how blessed I am. I am 61 years old and by the Grace of God, I'm in EXTREMELY good health and physical condition. Other than a few broken bones in my young adult years, I've experienced no serious accidents or had any health setbacks. I try not to take it for granted and try to remember that this can change at any second.
Had I experienced anything debilitating at a young age, I don't know if I could have soldiered on as you obviously have.
