As I have reached a half a century old, I have come to the realization that it is severely pressing to focus on keeping myself well cared for. I was talking to a superb neighbor about this and he was saying there are a lot of ways to care for myself. He said that assume it or not, 1 of the best ways to help care for myself was to work on your Heating, Ventilation, and A/C system. That seemed like unnecessary advice to me because what does an Heating, Ventilation, and A/C system have to do with caring for myself. He explained it to me. He said that air quality is of the utmost importance because the air all of us breathe largely determines how well we do on our checkups. If all of us are breathing in terrible air quality all day and night, naturally we’re going to get sick. If all of us were breathing in deadly gases, all of us could actually die. So in order to care for ourselves, all of us had to change our air filters properly and have our Heating, Ventilation, and A/C systems diagnosed properly, however dirty ductwork is the opposite of caring for ourselves so all of us have to have our ductwork cleaned and not just forget about the ductwork and take it for granted. He said you should have the air vents and ducts cleaned at least every two years or so, but yearly would be even more likely to keep us healthy and to keep the air quality at good levels. He said it would be a smart idea to go out and purchase in a nice air purification system to further improve the air quality and use the air purifier every day. He then gave me a lecture about diet and exercise which is also vital to caring for oneself. He shared recipes he had that were full of vitamins and have helped him a great deal to help him take better care of himself. When I asked how he became so knowledgeable, he said he l acquired it from his health care worker.
