When I was in my forties I got lectured over the phone by my parents (!) about not riding the tougher horses. Very urban, non-horsey folks. As they were talking, neighboring ranchers rode by the window on a couple 3 year olds. They were both in their 80s.
Another friend, in his 80s, lived in a nursing home, needed a walker to get around, and had to have help from sitting in a chair to standing. He came to a branding and asked to rope a few. His son and grandson, with trepidation, put him on a horse. He put the rest of us to shame. He got both hind legs with every try and only swung his rope twice, every try.
I live around real good "bad" examples.
