Is it normal that i laugh when i am hurt sometimes?

You are laughing because ironically you think it's funny that how something like that can happen to you even if it hurts.

I agree with ajawson it is a defence mechanism. You would be suprised how many people do it. Some even do it while they are dying.

I just cut myself and hit my tendon didn't cut all the way but hit it and all I did was laugh then and all the way to hospital while they stitched me up I got seven stitches lol

It's a defense mechanism. I think it's a great way to deal with pain, as long as you're not a psycho.

yeah i do that too...especially when i hit my elbow. they dont call it a "funny bone" for nothing!
