I've been reading Will Self lately he is my favorite writer at the moment. I discovered we have something in common and those are the walks.
I found on youtube a video where he talks about long walks and the philosophy behind it.
I have to confess, it is very addictive as, while you walk, your body produces some chemicals which makes you fell GOOD. It's like taking drugs but you have to sweat for the pleasure of being stoned.
After a couple of hours of walking, you get a shoot of pure happiness.
Here are some grey photos from one of this walks.
