So if as a child I learn to send a signal to my hand to move out to catch the ball, the signal takes X microseconds to travel from brain down my arm to my and and "clasp"
But as an adult / teen my arm is now a foot or more longer. So the signal would take x+y microseconds to get to my hand - but if the resistance of the nerves reduces it's signal is faster and back to x microseconds
