I easily don’t guess how people survived without air conditioners, because I guess that I easily wouldn’t have survived without a central air conditioner. It is still impressive that there were people that thrived without an air conditioner, and did you guess that air conditioners have only been around for the last 100 years? Before then, there were certainly no air conditioners to speak of. The air conditioner is pretty new, & all the people fifty years ago did not have an air conditioner to speak of. It might not seem like things must have gotten done without a central air conditioner, but things certainly did get done without a central air conditioner. Think of all the appealing ancient things that were builtâ€¦ Consider the pyramids or the awesome structures around the world like the fantastic wall, all of these things were built without the help of a central air conditioner, & I assume that it is certainly amazing that these things were built without a central air conditioner. I wonder if people died a lot more often without a central air conditioner. I guess that hospitals & staff use central air conditioners a lot, & I wonder if that makes them important. Still, I guess that all the people did not have central air conditioners, & I guess that a lot of people had shorter life expectancies. I believe that it doesn’t easily matter if I assume about the past. It is not the past anymore, & most of us have central air conditioners now. I don’t have to worry about living without a central air conditioner.
