Interesting read! but I wont lie, I bet the number of people who don't do their own work would actually be a lot higher, I think some guys just don't like to admit(even to themselves) they don't know how to work on an engine
I may agree, when I was younger I did everything. Now I'm to busy and just not as energetic as I used to be. I still do most of the work but my boy is 15 now and soon he will be doing all the work while I watch and drink beer.
