halo my question is
why is a mentally handicapped person not like normal people
thanks for the help
It depends on what type of mental handicap you mean. If you are talking about mental retardation, they cannot learn or are slower in learning than "normal" people. However, savants — who often are not able to function at normal levels in most areas — have a limited area (memory, calculation, music, art) where they excel greatly.
It is a completely different thing, if you are considering psychoses, neuroses or personality disorders.
Please repost with a more specific description of what type of mental handicap you want to consider.
I hope this helps. Thanks for asking.
