Me too. I love sitting by an opened window and smelling the fresh Spring air come in, like it is right now. Sleeping next to an open window is also great, as is hearing the birds outside in the morning. I like being able to stick my head out and know exactly how cold or hot it is outside before I leave the apartment. In the winter when the heat is blasting nothing is better than cracking the window for instant regulation. Or just to air out the place with real fresh air, not mechanically processed air.
With everything sealed shut, to me it would seem like living in a mummy case or a fishbowl.
