I can believe our stomachs talking to ourselves 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 an odd feeling when the body is low on energy plus gently reminds you to fill it again. I assume if you go longer than that then the body will deliver you more drastic alerts about a headache or legitimately low energy but I never wait that long to find out. My heating plus A/C system can deliver myself and others the same alerts when it is time to scrub it such as the overflow pan in the air handler. My smart system has an alert on it when the pan is getting full as opposed to before when it would just overflow plus leak onto our ceiling underneath it. That was always a problem with our a/c because it was situated in the attic plus when the pan overflowed it would cause a lot of disfigurement to the ceiling. Now the smart heating plus A/C system has taken care of that by alerting us when the tube is clogged plus needs to be cleaned. Occasionally the water gets mildew in it plus causes the drain tube to clog which then causes the water to back up in the pan. I’m ecstatic that the heating plus A/C business has figured out how to alert us instead of causing more troubles when it flows over the edges of the pan which holds the water inside safely. Those heating plus A/C engineers are the best it seems.
