I never wear a seat belt it is buckled behind me I hate the damn things!!
There is one thing you can do to prevent traumatic brain injury from car accidents...
That one thing is deceptively simple. Wear a seat belt. Wearing a seat belt especially if you are driving or sitting in the front passenger seat in a vehicle equipped with air bags will keep your body from thrown from your seat and crashing through the windshield.
A traumatic brain injury can have lasting negative consequences in your life.
