ALL YOU PEOPLE THAT SENT ME PM's TELLING ME TO SHOVEL HARDER, SHOVEL FASTER CAN JUST GO TO HECK! 
Just for fun (???) I did a google search
snow shoveling deaths and limited it to the past month.
This looks to be a good article -
Medical: Snow removal raises risks for shovelers.
"There's little doubt that snow shoveling can kill. Published studies based on death certificates and weather records in Massachusetts and Michigan have showed that heart disease deaths generally and deaths from exertion-related cardiac arrest specifically rise by 22 percent or more in the weeks during and after a heavy snow."
I would rather die peacefully in my sleep like my grandfather. Not screaming like the passengers in his car.
