Glad you are back and well. That video should be a real eye opener for everybody. I fell about 22-25 feet in Jan 2007 from a double maple that looks very similar to the tree in the video. I was taking a stand down by myself. I remember falling and landing and that was it. Not the 6 mile drive home, not the ride with my wife to the hospital, not the expensive helicopter ride to Columbus, nothing. Next thing I remember was waking up in Grant Medical Center. I was lucky and have a scar about 12 inches down my chest to prove it. It can happen to the best of us. Wear those safety belts.
