Down-syndrome and be smart?
Theres this guy at work who looks like he has an extra chromosome. He looks really weird and makes weird facial expressions. But he actually seems quite normal socially. He sometimes seems abit immature and he doesnt drive. But he always holds a conversation well with groups, he jokes alot, and if he didn't have this weird look to him Id never think he had anything wrong with him.
Can you have down syndrome and be reasonably intelligent?
