I can guess my stomach talking to myself and others telling myself and others it is time to put some energy in the system.
It is interesting how the body has these signals for you to take care of it.
The stomach gives you a different feeling when the body is low on energy and gently reminds you to fill it again. I suppose if you go longer than that then the body will give you more harsh alerts, akin to a headache or honestly low energy but I never wait that long to find out. My heating, ventilation as well as A/C method can give myself and others the same alerts when it is time to scrub 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 my ceiling underneath it. That was always a worried complication with my a/c 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, ventilation as well as A/C method has taken care of that by alerting us when the tube is restrained 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 also enthusiastic that the heating, ventilation as well as A/C corporation 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 licensed heating, ventilation as well as A/C engineers are the absolute best.
