Yeah but (as any addict can tell you) pretty soon you'll develop a tolerance and it won't be enough. A casual 5 mile commute turns into a 10 mile detour turns into a 20 mile hammer. Pretty soon you're riding centuries and sneaking out on your spouse for "just one more" spin around the block!
Maybe we need a 12-step program: "Hi, my name is Caloso and I'm a cyclist." "Hi, Caloso!"
