What is the peak age for horse riding?

Every age is a good age for a horse as long as he has a loving, caring human. With better medicines and vet care horses are living longer, healthier lives. Horses are now living into their 30's and beyond. But from 5 to 15 are great years for your equine friend. He will no doubt look his best, shiny coat, clear eyes, strong legs and hooves. As he ages and you see some gray on his muzzle he will still look great to his person.
