I have wondered how people survived in the old days before modern heating, and air conditioning. I mean, how did they do it? With extreme weather in some parts of the world, there had to be some way folks were able to keep cool or stay warm, when needed. If there wasn’t, it doesn’t make sense – why didn’t people die off at a young age? The mystery of no heating and air conditioning in those days evokes my curiosity and imagination. It is tough to find any information on the Internet about it. Where can I even look to find out how people survived in the early years of the world without heating and air cooling? I don’t know. I know the very first form of heating was a lukewarm water boiler; But beyond that, I know nothing; How was air cooled? Fans were not the answer. because if it was ultra hot, a fan would do nothing but blow the heat all over, making it worse. All I know is I am glad that we have modern heating and cooling today. It is what I always rely on when the weather is bad, with too much heat or too much freezing hot and cold temperatures. Heating and cooling is a larger part of today’s world than many people even know. If you truly sit down and think about it you will see exactly what I am talking about! It truly is one of the many mysteries of the world!
