This article had had a very different lesson for me: Critical thinking requires application. I inline-skated as a kid, or "aggressive inline" the sport was called. I wore my wheels down to such an angle that I had worn through the blade frame and made it to the bearing. I didn't have money to replace them so I just pushed through it quite literally. This caused me much teenage angst, but with money from my first job, I bought Randy Spizer II signature boots and all the kit to get them rolling. $750 Australian Dollars, phew. The new frames let me run "freestyle" wheel configurations, only two wheels on each blade with the two middle wheels removed, so a pack of 8 wheels was actually enough for two sets of skates. That gave me a backup set for when I eventually wore through the wheels again. It was still an ongoing struggle, but I was better off having solved the problem with money. Upon reflection, I never once thought to rotate my wheels. I just wore them until they pretty much crumbled off the rim, then replaced the now very unusable wheels.
