I can feel our stomach talking to me telling me it is time to put some energy in the system.
It is simply interesting how the body has these signals for you to take care of it.
The stomach gives you a bizarre feeling when the body is low on energy and gently reminds you to fill it again. I feel if you go longer than that then the body will give you more dire alerts about a headache or actually low energy despite the fact that I never wait that long to find out. My heating and A/C method can give me the same alerts when it is time to clean it such as the overflow pan in the air handler. My smart method has an alert on it when the pan is getting full as opposed to before when it would just overflow and leak onto our ceiling underneath it. That was consistently a serious concern with our air conditioner because it was located in the attic and when the pan overflowed it would cause a lot of damage to the ceiling. Now the smart heating and A/C method has taken care of that by alerting us when the tube is plugged and needs to be cleaned. Occasionally the water gets mildew in it and causes the drain tube to clog which then causes the water to back up in the pan. I’m cheerful that the heating and A/C company has figured out how to alert us instead of causing more problems when it flows over the edges of the pan which holds the water. Those specialized heating and A/C engineers are the best.
