Convection is a product of gravity. Cold air sinks because it is, in bulk, less dense than hot air, or hot moisture laden air, which is forced upward until it finds air with similar properties. Thus, I have no way to understand your question about clothes, you could rephrase perhaps?

As for where to live:
- NOT California
- NOT Along the coast
- NOT Airconditioned (I hate the things, the dry air and shifting temperatures fuck up my sinuses)
