There was a 18 year old gelding doing campdrafting at Equitana this year :) Older horses don't necessarily mean they are unsound/don't have long left in them.
Sonja Johnson (an Aussie olympic eventer) competed her horse Ringwould Jaguar in Olympic level SJ, dressage, and XC until he was 19, and even then he only retired because he'd won everything! Haha :)
I ride a 22year old STB, who goes to Pony club for 5 hours without ill effects, and jumps 60cm (maybe higher, but I can't go higher)
In my pony club group, which is of older girls with reasonable experience, the youngest horse is 16! All of them can jump 60cm and do social endurance rides and all sorts.
BUT some horses are unsound by 10. So the 16yr old could be really unsuited to your needs.
As with all possible purchases, you should get a vet check, that will tell you everything you need to know :)
