Jesus, are you for real ?

I am not at all saying its about how clever people are.

Just because you and I are knowledgable and have the abilities to work with engine managment doesnt mean others have, want or need to do the same.

Everyone in life has there own skills and interests and sometimes you have to pay someone else to do something you cant do yourself.

As an example, I dont grow my own food but could do it if I wanted but its easier for me to go to Tesco's
