JPPE,
With very best wishes for a full and speedy recovery. I'm sure most of us have stories to share relating to health. I think it's a byproduct of aging to recognize that we are mortal and the complexity of our bodies. Cheating the aging process by staying in shape is physically, mentally and emotionally healthy. Can't imagine being my age, very close to 60, and taking good health for granted. It's easy to temporally forget when things are good, but unfortunately there are regular reminders. Keep the faith, back in the saddle when you can.
