Agreed, stupidity is NOT ignorance. A lot of people use that word without realizing that it can only be applied to very, very few people in this world.

hmmm interesting... i just hit 21 years, so my frontal lobe development is in its prime, yay

I do have a friend who is well, pretty immature for her age. She's 23, but somehow her actions and behavior is so irresponsible. She even got cheated out of her semester fees (Rm1k +-)by a stranger, who took the money right out from her hand.

Do you label this kind of person as stupid then?
