No laws against it.
children might fall out!!!They legally can't open their windows? WTF?
Holy shitchildren might fall out!!!
My German friend finally broke down and got a mini split AC. I've also met Germans that think using an air conditioner will make you very sick. That conversation was weird.
They visited Florida last summer and we stayed near them. We went to their place and it was like 90 fucking degrees inside. I asked them to please for the love of God turn on the AC and they got all weird. They insisted they visited Spain and after walking into the cold room while sweaty they all got sick. Wtf.It's related to the belief that opening a window will cause a "draft" which will also make you sick.
