Couple of questions:
- How long have you been married to your wife?
- Why would you give up something that brings a solitude unattainable through a car?
After thirty-nine years of riding I would suspect your wife already understands your passion. If it is for health reasons then that is entirely another issue. I am looking to purchase another bike. Sorry, once it's in your blood there's no denying it (I've already tried do, and it doesn't work).
