I never take rest days unless I'm injured or really sick, or if I have a killer work day with no time to spare. I've taken 4 rest days this year and 9 total last year. I've been doing this for years and haven't had an injury since marathon training in 2006. (it wasn't an overuse injury.) I'm 43.
Instead of a full rest day, you could do something that is much less intense than your usual routine. If I'm very tired and super busy at work, I slip down to the office gym and do 20 minutes on the elliptical and that's my only workout for the day. Or sometimes I'll do yoga and skip the cardio or weights or anything else. Or you could go for a longer walk than usual, or hiking with your kids.
This is really just a mind game, your 20 minutes on the elliptical could be someone else's hour long walk. The takeaway for OP is to reconsider what you qualify as a rest day, which is what works for you. Your body will force you to take it easy if you work it too hard and don't allow it to recover, especially as you (and I) age. Somebody might consider an hour in the pool, lower intensity, zero impact as a rest day while another person would consider that a lighter workout.
It's all in the head OP.
