How much pain can a human body take?

Here’s another story about how I try to destroy my body: Tonight when I was getting ready to go out, I chose to use my flat iron at 180/360 degrees Celsius/Fahrenheit. well that’s the normal heat I use to get my hair straight. I had bought a new dress which would look great with perfectly straight hair. I was working my way through thousands of layers of hair when I somehow - don’t ask me how - grabbed the iron at the part which heats up. my left ring finger and pinkie seemed to hurt the most. well they still do! now I’m sitting here typing with one hand, in my pyjamas obviously not on my way to the night club. And I wonder how much pain can i take? I never had such pain. it’s fucked up. its not even possible to “accept” it, as soon as i take off my fingers from the ice cream carton i feel like screaming is the only thing that can distract me from the pain channeled into the bubbles on my fingertips. 

And yes - I will use the flat iron again!
