What are the causes of osteoarthritis at an age of 36? - osteoarthritis more condition_symptoms

Please help me find the causes of osteoarthritis is with my brother. How can this happen so fast, I'm surprised, though often associated with age? My brother is in good shape and keep fit.

Cartilage can push on? For how many years? I know that growth is very slow.

Please tell me ...
Thanks
