Swimming 3 times a week for about 45 minutes changes the body and mind.

And is a little addictive like ex. running.

Background: I've been swimming for the last few years for about 10-20 minutes twice a week and I've experienced the changes.

Switching few months ago to more intense sessions led to dramatically higher rate of the change and I start to think about the ways of sustaining this. For now I've bought the swimming paddles and this works.
