When I was but a small child, in the dead of winter, I stood with the door open.

Hmmm, doors cause Global Warming®...

You know, that could be the basis for a very lucrative grant application!

No. Doors do not do anything. If you ever watch crime shows, you will learn that someone died, and their door was ajar. Jars are the problem, not doors. When you try to make a door out of a jar, you are about to die.
