For my part I'd like to say that 'hardcore' and 'stupid' are a matter of opinion. Posters here have said that stupid is when you risk serious injury, have little or no safety margin. I disagree, I have been in situations where I had very little safety margin, hiking in -40 temps, I summited a mountain in Alaska in hurricane force winds, icy traverses and climbs, surfing, skydiving, etc. some of the descents I do on the bike prove that I can eliminate my margin for error when its 75f outside. To some I am not even close to hardcore, to some I am stupid. But to me its precisely the times when my life was on the line that I felt the most alive. I don't mean to insult anyone who doesn't risk life and limb for sake of experience, but I personally advocate doing so.
