alt Hacker News> Sitting and thinking for 10 minutes about snowboarding when your knees are blown out is 10 minutes you could have used differently.
10 minutes doesnt sound like much of a loss, even if you do it every day. Maybe it helps you empathize with athletes, or if you get nostalgic/wistful, it helps you explore the range of emotions, which is fine as long as you don't get stuck with them.
Sure, I was being extreme. The danger is getting stuck, like in “Glory Days” by Springsteen, or Brando in “On the Waterfront.” People especially get stuck on their high school years.
