It's good to hear all these "getting old" stories... I hope that I can keep doing things when I am older. I am 38, so I some good years left because I quit drinking. I don't care how how old you are ... smacking your knuckles on flywheel gears is annoying. Or how about smashing your finger when sliding your creeper wrong.... love it. My all time favorite: working under a dash laying upside down/backwards w/ my legs falling asleep, stuck over the non-sliding diagonal door roll bar... man, that is pure joy... clastraphobia at it's best.
