My wife hates to sweat (her words) and loves to tell me about the items she bought on clearance for <$5 (about which I couldn't care less). You may wonder how we hooked up, but we do have many common interests (swimming, board games, band) and now we have a daughter. One of the biggest problem is that I have 5 hobbies (biking, ultimate, tennis, chess, computer programming) and she has none (she scrapbooks and crosstiches, but claims that since she does that all day with our daughter, they arn't hobbies). This causes lots of stress since I generally take 1 day out of the week for myself and half a day on the weekend. I then commute by bike to get my bike time in and she feels she never gets out of the house. When I offer to watch Brenna (alone) for a night, she has nowhere to go and doesn't want to do anything.

I don't thing it's about biking per se, it's about everyone having both personal time, and time for each other. Some people like 100% personal time, others are the opposite. I think I prefer 60% personal/40% together and my wife prefers 90% together/10%personal.
