I wonder if it is related. In elementary school, I noticed that the children with peanut allergies were all placed in AIG advanced classes. Kids with autism tend to be smart. Blind people get better hearing.
I heard it's because with less brainpower in certain parts, it allows other parts to develop better. That explanation may be total BS, correct me if I'm wrong. Does not apply to the blind kids, that has a separate explanation.
