Every time I take the dog for a run, he comes back with the biggest smile on his furry little face.
As for me, running is stress relief now. It's my way of getting rid of all the energy that would normally be put to use by strangling the shit out of some idiot.
And to think that a decade ago, I was smoking a pack a day and saying that I would only run if people were shooting at me or screaming for me. See kids, you CAN change your life!
