There are similar things, and it really won't help anyone. As for them taking this for granted? They don't. They think that if they see themselves as "gifted" in that area that they are just better prepared, etc... The are fooling themselves, but they don't care about stuff they don't know they have lost. You can't convince them of it.
I have TRIED! I have PROVEN them wrong! STILL, they act like I am nuts. I was called arogant and racist because of how I held my arms. I pointed out someone NOBODY dared call arogant, etc... And mentioned that HE obviously was. When everyone gasped, and he said *****WHAT*****? I asked him why he held his arms that way. He said just to rest them. The SAME thing I and EVERYONE polled said. Yet that wasn't enough!
How could a mere book do any more?
