I think we need to realize that increasing age affects so many aspects of our lives. I have had horses for 43 years now and while I love my horses the same as I did at 12, things have changed.
I definitely have become a “fairer weather rider”. I am out to feed , clean and care for them 365 with no problem, but ride in cold weather? Up until a few years ago I would ride no matter what the weather as long as the footing was good. Not anymore.
That is ok.
