I'm not buying this argument - use it or lose it isn't even true in physical sense - sure if you stop working out you lose muscles/strength - but once you start back up the rate of progression is like 5x.

It is very true in a physical sense. "Use it" results in neural pathways being formed. What happens when you dont use them?

With exercise and cognition alike, the concern is motivational. If you let yourself get out of shape, it can be very difficult to rebuild the habits required to get back into shape. You get drawn into a bad local maximum (e.g. prompting everything, driving everywhere) and find you don't have the energy to get out.
