Automotive repair no-no's

This just keeps getting better and better, I thought I was the only one that was prone to brain freeze. Oh I almost forgot, (again) when you young lads reach the golden years you can all, and I mean all, look forward to short term memory loose. That's when you take out a bolt, a spark plug or a wrench and set it down and forget where you set it. Hell, last night I took off my glasses and it took me 30 minutes to find them. I'm going to hang a bag around my neck to put everything in next time. ](*,)
