If it makes you feel any better, I ride a trail ride every year in April and Oct. Big ride, always 150-200 people. I know a lot of the regulars, horses and people. This April there was a new lady there, 62 years old, on a 3 year old, very green TB. She was a confident rider, but that was a LOT of horse. Anyways, he bucked her off and as I and many other rushed to her side, she sat up and dusted off. The nurse asked her if she was hurting or numb anywhere. Her response was, "Honey, I'm 62 years old. Everything hurt when I woke up this morning!" She gathered herself back up and got right back on him and set his butt straight. He was an angel the rest of the weekend.
No one is too old to have a great relationship with a horse or ride with confidence.
One is closer to God's heart on a horse than anywhere else on earth!
