Hey Rob, I'm sure that you not alone. I know that Chris has other hobbies that he enjoys that he would like me to participate in eg. Shooting, but it just doesnt interest me. Just like Chris dislikes being dragged into the changing rooms when I'm on a shopping mission.
You mentioned the helmet hair issue, which I don't enjoy either, but I found a solution in a silk head sock that can be used in a number of different ways. The sock can be used from everything to a balaclava to a bandana and even a neck warmer and a mask if it is dusty or cold.
Perhaps a deal could be done between you and your wife, look at a hobby or interest that you both have and don't share and perhaps a little "I'll try yours, if you try mine approach", may set the wheels in motion.
Good luck.
Jean
