Why do I not bruise?!
Question:
Why do I not bruise?
Is there a medical reason for this??
Even when I feel down the stairs I still did not have a bruise!!
Answers:
Bruises are caused by blood clotting under the skin due to ruptured capillaries. So either you have well hard capilaries, or aren't damaging any when you land, or your blood isn't clotting.
If it's the later start to worry.
