Worry more about the auto accident going to your hunting area. Worry more about being overweight and in poor health. Worry more about getting shot by a fellow hunter.
I think you should be saying worry "also" about these things. Not wearing a safety belt in a tree stand is simply taking an unnecessary risk that could have catastrophic consequences. Although it won't gaurantee you won't be injured it most certainly lowers the chances of a serious injury. It can also double as agood dragging tool. Remember ANYBODY can fall including you.
I suspect The Mindto beno more than 14 years old. His body may be but definetly not the mind. I'm envisioning a Bevis & Buthead type.
