My new favorite thing to do I bike and run a lot, and I also get held up at red lights quite a bit during both. Instead of cycling through the stats on my Garmin, I've taken to staring at all the fat people as they drive by. The ones that aren't zoned out staring at their iPhones are usually looking at me, so I just glare right back, with a slight look of disgust on my face. I make sure they see I'm taking a good, hard look at them, and then they usually break eye contact and look down. Just one more person out getting some exercise, barely breaking a sweat in the middle of summer, while you're stuffed into your SUV and having trouble breathing 'cuase that seat belt's just... too... tight.
