Please folks... absent mindedness does not mean a lesser intelligence. I cannot believe how many posters are mistaking the term for this. It is associated with genius more often, e.g. Einstein, Da Vinci, Aquinas, Galileo, etc. and in recent times serious studies are showing that absent minded and wandering or daydreaming kids, the ones that in my days that were constantly being called up in class all the time, have actually more intelligence.
Imo, I think the part of the problem is we as a society tend to think more in extremes because that's what we see in the media, ie.savant vs imbecile, both could arguably be considered autistic to the layman. It's only been in recent years where the levels of intelligence in all three of those examples are becoming better recognized through advocates demanding better education for both their patients/loved ones and the general public to help those persons cope with life past their support systems lives(parents dying and leaving an adult with ie. Down's or a more severe level of autism on their own). It's like many still think all jocks/blondes are stupid and all geeks/nerds are genius....
