i have been hitting the pool very often of late. i have to say - it is rather addictive. i only hear the splash as each stroke breaks the surface of the water. the rhythm is at once hypnotic and calming, and i'm left to my own thoughts, alone in my own world (that is if nobody swims in my way)
lately, i also run a fair bit, but i am rather cautious, because of my knee injury, so i just push myself to 80% - but it is theraputic as well - each stride, each breath becomes louder than the traffic around as i focus on each pace to the finishing line.
i enjoy this peace, even if it is just escapism.
