How do can you crack your sternum?

Question

i've cracked my sternum before, but I want to try it again... i have the feeling it needs to "pop"

Answer 1

You are joking? I have cracked my sternum by falling out of tree flat on my chest on a cement slab and it is no fun. That weird feeling takes a long time to go away. I had the same feeling and often it would pop on it's own for many years and it finally all stopped.

Please don't go trying to breaking bones. It is not healthy. It sounds more like you need a good "popping" across your head to knock some sense into it. This is just plain foolish thinking.  

Answer 2

CPR, and the Heimlich maneuver can crack your sternum

Dont DO it though
