The brain likes to be efficient and so even as its strengthening the pathways you're exercising, it's pulling - it's weakening the connections in other ways between the cells that supported old ways of thinking or working or behaving, or whatever that you're not exercising so much.

The working classes may be injuriously degraded and oppressed in three ways:1st - When they are neglected in infancy2nd - When they are overworked by their employer, and are thus rendered incompetent from ignorance to make a good use of high wages when they can procure them.3rd - When they are paid low wages for their labour.
Robert Owen
Living, just by itself - what a dirge that is! Life is a classroom and Boredom's the usher, there all the time to spy on you; whatever happens, you've got to look as if you were awfully busy all the time doing something that's terribly exciting - or he'll come along and nibble your brain.[32].
