Very interesting. You put words to my thoughts. I've noticed this too on some adults but also in children (2 relatives, boys age 10 and 12). Their eyes are empty, they are completely functional, average intelligence, bodily functions fine but there is that *something* missing deep inside them... I mean, they are fine but other than play videogames and interact when needed they are mostly like automats... one is currently taking meds for add and the other is not but still it amazes me the lack of **life*spirit*fire*spark** this humans have... I noticed that but never thought anything other than they were the product of their parents but now this theory adds an interesting twist to this situation...
Why do you think this is happening? are they some other dimension beings or just too self absorbed and egocentric?
