Tuned into Homeostasis

Homeostasis in short is just the body in it's self trying to maintain normal balance of weight, hydration, energy (food), oxygen, etc. But this type of regulation if the body is a bit different for each individual person. You see, some people may have more of an active life style leading to more of a need for calories and water, and varying weights because of exhaustion of the body after work outs. Then there are others that may not be as active as most and this leads to less of a need for calories (fuel) and also water for that matter. Ever wonder how you can eat 3 meals a day every day and not be huge? Well homeostasis is the regulation of using up all those colories throughout your day and preparing it's self for some sort of action. Homeostasis, the wonderful action of the body that keeps you finely tuned like one of Eric Claptons guitars. But with different guitars comes individual tuning.
