Ironically, Thoroughbred mature SLOWER which is probably why so many break down. They, much like stock breeds, have been bred to APPEAR "fast maturing" and it's a lark. No horse has ever fully matured before the age of 6, and the taller the breed, the longer it takes for everything to fully fuse.
In virtually every breed, the leg joints are fused between 2-3 years old. So if a racehorse makes it to that age without damage, they may have a shot at not breaking down due to joint issues (or having them in a later career). HOWEVER - racing tends to not be as hard on the spine, where jumping is and the spine is the very last thing to fuse.
So jumping a 3 year old Thoroughbred is probably even stupider then racing it.
I hope God tells her to smash her computer with a sledgehammer.
