Here in France (especially in my aera) we see a lot of "veterans"
rugby teams.
They play full contact (to not say "hard, bad, full contact"
), it's a very tuff game too.
I also played rugby when I was younger. Broke my knee and had surgery on it. Stills hurting the rainy days
All that to say if you want, you can. Except of course medical exceptions. Just go to the doctor to take advise on it.
