I got my "oldie but goodie" when she was 19. I didn't know at the time that she WAS 19, and I thought she was at death's door, then.
However, "Gramma Pony" as she was then called, rallied and is still here and I now know her true age, which is 32 years as of this past July. She is the healthiest horse we have, and my husband's favorite.
She's also mine for many of her qualities, not the least of which is her quiet patience tempered by a cheeky sense of humor and entitlement.
"well the horse has lots of exxpieriance but it may die soon."
Don't tell Gramma that! She's got a grandbaby to welcome in February: her 7th for us (and I know she has a few others out there by the studbook).
At those ages, I'd be more than happy to consider them if I were looking to buy.
