Or extended family used to go on camping trips in a state park in western New York every two years and one year the heater in our cabin broke. When I asked my mom if we could just sleep in the car all night, she said no because then we might never wake up. She then explained that car heaters worked differently than house heaters and if they weren't moving they gave off a poisonous gas.
Until I was about 12, I would hold my breath when our car stopped at a stoplight in the winter because I thought if I breathed too much, I would fall asleep and stay asleep forever.
