I have a  friend named Jeff Dobkin (www.dobkin.com) who has a fantastic tip on preventing brain damage.

This was pulled directly from his website:  http://www.braininjuryfoundation.org/

The Dobkin Technique

The Dobkin Technique is an emergency time-buying procedure to trigger the Mammalian Diving Reflex and delay brain injury and brain death: apply cold wet cold compress to the eyes and face of the victim. Temperature of compress must be 58 degrees or cooler.

This simple procedure works immediately to begin to delay brain damage and brain death. This is the same reflex that delays brain damage in cold water drowning victims.

Please take the opportunity to visit his website

I encourage you to please forward this page to all your friends, you may never know when it could save someone’s life.
