I marked your comment as helpful, Dr. Beckerman. You see, when I was a kid, and even up until I had my 4th child, I could swim underwater for great distances, do contortions, backflips, lift as much weight as most men, (my husband's Lincoln welder was small business for me to lift), and I always walked long distances every day.
Scoliosis and osteoarthritis have gotten the better of me, I'm afraid, and when I quit smoking twice, I gained over 60 unhealthy pounds.
