The number 1 cause of death from chocking is having some sort of obstruction of the air ways.

I’d imagine a common chocking death is when a vehicle rolls and crushes someone.

And the #1 cause of death is dying.

I would expect a chocking death to be some kind of crushing hazard. Don't know why anyone would chock an airway but it makes sense it would lead to choking.

The number 1 cause occurs in more cases than the number 2 cause.
