I wish humans had built in night vision

Humans should have night vision. Cuz it sucks when you're walking in the dark and nail something with your shin and it kills! It wouldn't happen if you could actually see in the dark! Or when your friends think its funny to scare you, and you're walking through the dark and they basically give you a heart attack. And if you could've seen them, this wouldn't of happened! I know it's not that big of a deal, but it would just be really helpful. We've all had situations where we couldn't see anything. But if this was true, I guess horror movies would probably cease to exist.. and I like horror movies. So let's just forget about this idea ok?
