Yes it is a lie that with enough adrenaline a mother could lift a car. With enough adrenaline, I doubt anyone could singlehandedly lift a car, but it was amazing to see so many good people banding together to save a man trapped under a burning wreckage.
People, when banded, together are able to do anything. This video is proof of that. The holiday's are a good time to remember just how amazing the human spirit is.
