Haha Blu I don't think it works that way
I had a good laugh though lol. You should know each horse is different.. But um... one of my daughters is riding a 2 and a half year old...does that mean she is extra expirenced?? Lol
Anyways, yes huntergirl, as long as the 18yr has good health, good conformation etc I don't think there is a problem. I wouldnt be doing 1.2m jumps though. I would stick to around D grade Showjump (70-1m). Just until you get with things again. I know 22year olds still competing in B grade, which is over 1.2m. But they don't do as well as the younger horses.
