So back when I was 12, I recall riding my new mountain bike that I had purchased at Wal-Mart with my allowance. I had just started waving at some neighbors in their front yard-----

--12 hours and 1 out of body experience later--

--woke up in county hospital with severe concussion, unable to stand up without fainting and/or puking, later found out to be from the bruising my brain had undergone. About 6 hours after that and the 1.5 hour ground ambulance ride to the nearest MRI instrument, which showed the excess fluids inside my cranium and proved to be enough motion for me to puke some more.

Once at the larger hospital, I had received a mylar balloon with silver backing and was able to see the large black eyes I had received from my impact - imagine one half Jackie O. sunglasses, the other half John Lennon's and that's how my face looked.

Turned out that I had pulled an Endo and lost some memory prior to the event, which explains why all I remember was waving at my neighbors. Also, I had fainting and dizziness for several months following that.

Moral of story: Don't try B.

Also, that was back in 1992.
