I got lucky. In fact, I'm the luckiest SOB, maybe in the world. I've told this story before, but my wife-to-be had asthma when I met her. I'm basically an engineer. So I fixed it, and in the process got me a partner and a stoker. We are joined at the hip, and I can exercise all I want, because she's healthier than I am, only 3 years behind me, and usually with me, bike, hike, gym, etc. She's also almost as nuts as I am. Like crazy enough to do RAMROD on our tandem when we were 69 and 66. "No retreat, baby, no surrender."
