18?! This is the switch age when they start reverting to three year old behavior again ;)
If your horse is working fine, then keep at it. I hate people who stick a perfectly workable but older horse in a field because it's nicer for them... And then the horse stiffens up, loses muscle tone and looks like a Halloween character.
I find as they get older, or weather cools, a longer warm up and cool down and more rest periods make for a happy Goldie oldie. My 21yo school master was ridden for an hour a day, he is still competing with his new owner ;)
