Most people "back" horses at the age of three, although I would recommend waiting until at least four, when the horse is almost finished growing and they is less risk of bone/joint damage. Start slowly, of course. Wait until he is five or six, at least, before any galloping, jumping, advanced dressage, etc.

Your joints will hurt if the synovial fluid hardens and joints become stiff.
Because they have low freedom of motion. It is hard to push a shoulder a way it can't go, but pushing backwards on a hinge joint can cause a lot of damage without a lot of force.
Repetitive Strain Injury or RSI.
If you have an injury around a joint it would be best to let the damaged tissue settle down and repair itself before putting to much force on it. If joints don end up exactly back in place after an injury there is risk of causing cartilage damage. This is called osteoarthritis.
An elliptical machine is basically a cross between a treadmill and an exercise bike. The motion of the legs on this stationary machine simulate walking or running and provide an excellent cardio workout without causing excess pressure to your joints.
The medical term for inflexible joints is "ankylosis." This condition can result from inflammation, injury, or other underlying health issues, causing stiffness and limited range of motion in the affected joint. Treatment may involve physical therapy, medications, or surgery in severe cases.
If you have an injury to one of your joints there is the possibility that the injury to the joint is only part of the problem as as one or another form of arthritis may have been causing damage to the joint before then. This sort of damage can have a bearing on any compensation claims made as a result of injury's where there is litigation.
Yes it is not uncommon for OA to develop at injured joints.
without joints, you can't type, run, and all sorts
Yes it will literally eat out the mortar joints causing structural damage eventually, remove and repoint joints.
