Every living thing is made up of cells, and the cells are very busy. They're always doing something, either taking in new nutriants, or getting rid of waste. So, if all this is going on, then why don't we feel it right? It's because the activity is so small and faint, we don't feel it. Either that or we're just used it so much, we don't feel like we feel it.
