Water skis are not meant to be used at midnight
Canoes are not meant to be used down a snowy hill
Bikes are not meant to be used off garage roof
Shopping carts are not meant to be used down steep hills
List goes on forever - people get killed many ways. Been a few die from being hit by a baseball in the chest - in what is considered a safe game.
I send this one out to him - RIP.
