On a somewhat similar note to the post tailbones, One of the scariest 10 second pains is getting the wind knocked out of you. As wikipedia explains it… Diaphragm spasm that occurs when sudden force is applied to the abdomen which puts pressure on the Solar plexus. This often happens in contact sports or by falling on the back. It results in a temporary paralysis of the diaphragm that makes it difficult to breathe. Why must this happen? I have been breathing for 17 years and all of a sudden I no longer can. Mostly everyone goes through this and hopefully the Irony of the Posts title Catches everyones attention.
