Have the likes of Nadal, Djokovic and Murray highlighted that you can actually push your body too far in search of excellence. Tennis especially seems to have an issue at the moment of the top players being plagued with injuries and not minor ones. Maybe it's always been there or is prevalent in most sports, but constantly having surgeries and injections just to play cannot be healthy. Rugby has rightly focused on the long term effects of head injuries, but some of these players could well have a poorer quality of life once they retire as well.
