ITT we recreate man to be perfect.
Fix any flaws you think the human body has or add anything that you think would generally improve mankind.

Alright so i have a problem that i'm going to fix.
You know how it's impossible to know if a sound is coming straight ahead of you or right behind you?
Well to fix that i think man should have another ear on his forehead, so that if there's a sound in front the front ear picks it up You'll instantly know if there's something up front, rather than the vagueness of it maybe being behind.
