i change mine
the hour after the wisdom tooth removal when the novocaine wore off and the percocet was still kicking in... that shit was BRUTAL.
why do you guys feel pain? It sucks.
Nerve endings send impulses to our brain telling us theres something wrong, the pain we feel is our bodies way of alerting us to that. if we didnt feel pain, we would probably die very very young because we would never know anythings wrong with our bodies. at one point a
long ass time ago, most animals didnt feel pain, the ones who did lived longer and the genes that carried the stuff we have that gives us pain moved forward.
its one of the most useful evolutionary traits we have.. and one of the shittiest.
