For me, biking is a joy. So if I ever "don't feel like it" because of fatigue or illness, I don't go. Now running is another story. I can psych myself out of going for a run all kinds of ways. Sometimes I've pushed myself to do a run, and realized that I really was too tired or too sick, or yes, that really is a migraine...stuff like that. But biking is a treat, so if I don't feel like it, I don't do it.

It would be like me saying, "No, a piece of dark chocolate wouldn't help right now." I'd have to be sick to say something like that.
