If you choked and died, how long until someone found you?

My children would find me almost instantly. The older ones would still be asking me to make them food and drive them to their friend's house, and rummage through my pockets looking for candy money, and the younger ones would probably jump around on my corpse, pulling my hair and shouting in my face. By the time they all realised I was dead the house would be a complete mess, I'm sure.
