A friend took up riding in his 40's. Did numerous clinics with Parelli instructors. The man has wonderful patience and does great groundwork with his horses, but, his riding skills left something to be desired. He was on a 3yr old and wasn't listening to this colt he'd ridden a dozen times. By ignoring warning signs they got into a wreck. The colt was fine but he was seriously injured. Unless his testosterone was in high gear, with two younger women watching, I was surprised he didn't twig into the colt's signals as he was very good at reading them when doing groundwork.
