Qwiss I was a competitive ski racer, I raced internationally for a decade. Did my knee when I was a teenager and was never the same, but you get on with it, take a painkiller, condition as best you can, etc. The idea you're going to participate in any sport at a high level and stay clear of pain is fanciful. You've got to play to win, I'm not convinced by this idea that you can extend your career by not playing. In reality, you're just spreading a short career over more years, and the real risk is that you miss the moments you could've made if you'd been on the pitch.
Play. If you regret playing, you're in the wrong line of work. That's how I see it anyway.
