He's the same age as me... maybe one year older at 52. He's a classic sedentary guy, overweight, and with diabetes. A month ago he had a semi-serious heart attack, had two stints put in... his wake-up call.
His recovery includes a health managment class by his hospital, they told him to start exersizing every day (or else he'll have another heart attack and die... no reason to soft soap that kind of advice). His wife asked me about bicycles and I told her the usual stuff about LBS vs Walmart etc. offered my services for whatever. Wife said he told her he's never paid more than $300 for a bicycle and doesn't want to unless he's sure it's something that he can stay with. Later he got a used bike off Craig's List, not too bad, needed some maintenance. A couple days later he went to the LBS I recommended for the adjustments and came back with a new $700 bike with all the gizmos - computer sensor built in to the fork, computer-HRM combination unit... he probably hasn't discovered Garmin yet or he'd have one of those too. Anyway the LBS did a good job and sold him probably the same thing I would have chosen for him. Dr. told him not to get his HR over 110 (!) for a while, so he just rides the local trail with his wife (also not athletic but healthier).
Anyway, I'm cautiously optimistic that he'll keep this up, it's been fun watching him and I'd like to see him get in shape and enjoy a long life.
