"I read this large book about repair so I get a permanent bonus. Sweet!"
"I read this magazine about repair so I get a lot better but only for a few minutes. I guess after a few minutes I forget what I just read. ADHD much?"
Seriously, what sense does it make that a book gives a permanent bonus and a magazine gives a temporary bonus? I realize the magazines give a much higher bonus than books but the premise makes absolutely no sense. Reading a book somehow lets you retain the information as opposed to a magazine where you forget what you just read a few minutes later?
