Hi Peter C.,
First of all, congratulations on the good results from the heart exam.
Secondly, you have to get off the coffin nails. Now. Be like my grandfather, who quit cold turkey in 1964 when the Surgeon General's report came out.
Thirdly, do whatever you can to lose weight. If it means you can't ride for a year, then do something else for a year. I doubt a year is how long you'll be off a bike, but still... getting control and not letting obesity control you is the key.
And finally, if you want to talk, PM me. And if you ever find yourself in the greater Philadelphia, PA, area, we'll get together and ride if you like. Bet you can drop me!
