im pretty sure that if you went a week without drinking any water you would die or end up in hospital with serious Kidney/liver problems.

Have you ever had your toes start to freeze and couldnt warm em up for an hour so they just kept on hurting and hurting because they were so cold?
Ooooh god yes, this has always been a problem with me, sometimes the pain drives all up my legs, its torture alright.

Ever had so many painful experiences that you eventually became desensitized to pain? to nominal pain, not severe severe pain.
