As you get older you value silence more. Your nerves get jangled more easily. Loud music becomes less and less attractive. Instead of wanting to rev up, you seek ways to calm down. But I suspect the search for real silence goes deeper than just a desire to relax. It’s no accident that many religious orders have vows of silence. Only in silence can the soul unburden itself and then listen out for subtler signs, information from the unknown inner regions.
