For me I enjoy going to our Provincial Museum of Natural Archives and wandering through the displays at my own pace. No one to say go faster, slow down, stop here etc.
The outside of a horse is good for the inside of a man. I own several so that makes it easy for me but a person could always find a stable that could use a hand. Don't have to ride, even just grooming them is good.
I enjoy canoeing as we live right next to a lake.
That's my two cents.
