I am a dog attack survivor. Not to sound dramatic or anything, but it's true.
Two or three times a year I decide that doctors and internet articles must be right about exercise being good for your health, and I rededicate my life to becoming more fit for a few weeks. I log into my Nike+ app, lace up my running shoes, and pretend like I am going to register for an upcoming 5K. And honestly, I love it. Going from in-shape level zero to race-ready feels awful each time I start back to it, but after the initial week or so I start to enjoy and look forward to my runs.
