For me, only one time I can think of. I'd partially herniated a disc in my lower back the day before and decided to see if it hurt to ride. It did. When I finally got home, getting off the bike was not pretty. The rest of the time I've been glad I pushed myself.

Right now, however, we've got a lot of stuff going. I had hoped sending both sons off to college would free up riding time. But M-I-L's health took a downturn and my wife has had to move in with her temporarily till the family sorts things out and other arrangements are made. This has made it more difficult to get out and ride as I'm dealing with a lot of things she would normally take care of.

I do manage to ride when I can. Commuting to work by bike when possible, taking rides with my wife to give her a break from her mom, taking rides with friends from church (10 MPH average speed which was difficult for me at first) and, when I can manage, heading out on my own to crank out some miles at my pace.
