There is no doubt that mood makes a big difference in how we feel and how we act.
There is an old saying that laughter is the best medicine, and it is true.
Feeling sorry for yourself never got anybody anywhere, so laughing about life is helpful. Someone who is like Eeyore is never going to be well. Well, as true as that is, I say that the second best medicine is good air conditioning. In fact, the first air conditioner was invented by a doctor who was trying to keep his patients well and comfortable. This doctor lived in the south and ran a TB hospital. While he was watching everyone sweat and also watching the thermostat reading rise, he wished he could do something. That is when he thought outside the box. He got a box fan and turned it on. Then, he got a big block of ice and placed it on a tray in front of the fan. The box fan blew the cold toward his patients and the ceiling fans blew that coldness around the room. Hence, the first rudimentary a/c was born. Nowadays, you might notice that hospitals and doctors offices are some of the places with the best heating and cooling systems. That is because the air conditioner can keep germs away. Bacteria loves hot and humid environments, so using the air conditioner and setting the thermostat low helps decrease the growth of bacteria and mold and mildew as well. The operating rooms at hospitals have their a/c set really low. The thermostats in there are probably in the 60s.
