Thanks to those that provided a legitimate response to my post.

For those of you that think people can live without A/C in extremely
hot areas, what do you think about living in a house in the coldest
climates with no heat?

And sorry, but people did not live in the area where the house is 50
years ago in homes with no cooling. No A/C, certainly, but they had
evap cooling at the very least.

This brings up a different discussion altogether, but there can be no
doubt that development in certain areas is possible and only happens as
a result of modern technology. People in those areas then depend on
that technology to survive; e.g. heating or cooling of buildings and
homes.
