I enjoy swimming several times a week to rejuvenate my senses, obtain mental clarity and stay in shape. The swimming pool is the one of the few places where there are no everyday problems, no stress and most importantly, no phones. Everyone is just swimming.
Give it a try and you'll find it's a uniquely rewarding activity, in part because it is so hard to make progress at first and you really have to work at it. But like most things in life, trusting your strength and putting in the effort will get you there even if you swallow a bit of chlorine on the way.
