Rant number 121
Why do we need itches? What is the purpose of itching? What would happen if we couldn't itch?
I just don't get it, what does it add to things, really?
I like many people, suffer from psoriasis (not severe, but annoying) which means that one part of me or another generally itches every couple of hours. I really do wonder though, why the hell it needs to.
Is it some kind of exfoliation thing? removing top layers of skin that would otherwise choke me to death via my pours?
In my opinion that seems unlikely. At times I've drawn blood whilst trying to stop part of me from itching. That can't be right can it? Surely.
If we are a product of evolution - or even design (depending on your theological bent) surely at some point, the cavemen/missing link/monkeys that were too busy scratching themselves to avoid predators died out - leaving the non scratch ones behind? Why then do we need to itch.
As I right this rant, my right arm is itching just above the elbow - as if to taunt me further as I berate itching in general. I often get itches in this kind of spot - because it causes maximum inconvenience: generally it means raising my sleeve, unbuttoning my shirt etc etc.
I really do think that there is no reason behind itching. Its just a cruel trick being played upon us by some greater being/mother nature.
And now my foot is itching too.
Bloody itches
Rant over.
