Theres a hole in my shin that still hasn't healed properly after a couple of years and yeah, I thought I'd eased off, but I have recently taken up skating again, and I reckon that's actually more dangerous, especially when you don't heal so fast and you live next door to a concrete downhill skatepark... so to get over that I've built the death barge (tm) up again. And I'm shopping for bigger, faster, more launchable skis for this winter.
Counting the scars, the fear seems to go in 5 year cycles for me. Coming out of an episode right about now.
Basically, ease off all you want, but if you're the sort of person that enjoys hurting yourself at speed, eventually your unconscious mind will get it's way.
No reason, no conscience, no understanding; even the most rudimentary sense of life or death, good or evil, right or wrong.
