RE: Is it possibile to avoid totally injuries in sports?

There's no way to prevent all injuries in life, it just part of life... If you have an active lifestyle and enjoy sports with a lot of contact at some point you will get hurt. Life comes with risks, and if you're a professional athlete injuries and even death are part of the package. One must accept those risks before getting involved.

Just like diving, it's very safe overall. As long as you dive with a buddy you won't ever run into problems with air supply. The only way to get an embolism is dive deeply and don't stop on your way up according to the charts. That and never go cave diving, that is very dangerous! lol
