The things inside the human body are designed to keep us alive/survive. Each of them has own job basically. There are things for digestion, things for breathing, things for waste control, things for sensation, things for protection, and other complex things.
Everyday we introduce things from the outside. Of course we need to take good things, e.g. food, drink, air (and etc.). The things that ensure our body to stay healthy always. If not, the things inside the body will go chaos and break down easily and even turn into something deadly (e.g. cancer). Sometimes, we might have taken bad things. Those tiny little things come inside and do harm and even become deadly (e.g. viruses, bacteria). Many times, these things are preventable/manage-able.
What if things go wrong?? Either because of the things inside the body turned bad or those bad things from the outside. One would panic at first (I know) and desperately ask questions... "what is that thing", "how come", "can it be recovered/removed", "what to do", "is there another way", "how long it takes", and maybe "how much time left". Not too bad after awhile knowing the answers (if there is a cure).
Start wondering how the things inside my body are doing now. Really need to check it out. Take a rest.
