A question for all lads.

How come the internet is full of automotive forums with techs asking the same questions over + over ie
What does this fault code mean?
How does this system work?
How do I test this part?
Can I take this job on as I'm not sure what I need?
What should this read on live data?
etc etc etc

Yet when you ask who is going to any training/info related events there is either no responce or negative responce's like
I'm too busy, its expensive, I cant close up during the week to attend,its too far away etc etc

Then the same people moan about talk of codes been brought in to regulate our trade but yet make no effort to keep up to date.

I cant understand this reluctance to learn about the things we do everyday.If you don't understant something then surly you would want to learn about it.
Yes there is alot you can learn by yourself with the correct info on the system,and taking it apart to figure out, but there is nothing as good as being taught the system by the people who developed it or by the people who work on it weekly if not daily.

Explainations please as it makes no sense to me
