losing

To talk about the fact that a thing deteriorates when it is no longer fed. That there is truth in the saying, what you do not use you lose. But more in the way that there is no purpose to invest in a thing that is not used. It makes no sense to do so. It makes no sense to water a plant you do not want to eat the fruit from. Also it is how your very muscles work in your body how the more you use them the more they become capable for doing the task you repeatable give them. Building muscle and loosing muscle. There is no porpuse, no function, no sense, into having a musclar body packed with muscle, and not lifting a finger all your life. It is a waste of energy, it would be disfunctional for nature to behave like this. It would no be able to sustain itself if life would work this way.
