I have 3 of my own. Woman were I pasture board has 5 or 6, can't remember, but of mine, I have one that has health issues and was my son's. He isn't ridden.
Other older horse is "pink flamingo" and gets ridden rarely, mostly because I just don't take time to. After working at barn last thing I want to do is ride my own.
Youngest horse, my newest I bought because he is so cool. WP horse, but I got him for trail riding. I have rarely ridden him though, as again being tired/56 and I found after my oldest son was killed that I just don't have much get up and go, as nothing really has mattered. But getting better, and actually have made friends with quite a few women trail riders with good sense, so when trailer comes back from shop, will start trying to go some. Barn permitting of course.
If you aren't competing, and needing to keep horse on top of their game? You don't have to mess with them or ride daily, or even weekly.
Horses make me a better person.
