CWelch,

I highly support your quitting smoking. My Mom did not quite, and died at age 77 from lung cancer and emphysema. My Dad did quite, and lived to age 86. My Grandmother on Mom's side lived to be in her 90s. Mom did not get to see her grandchildren graduate from college, go to grad school and graduate there, and get married. Switching from smoking to bicycling is vital to your health, and you are to be congratulated about it. Keep posting, and we'll keep supporting...

John
