Last week I came across some great photos from an ad campaign launched by Adidas back in 1999/2000. They all have the tagline, "Runners. Yeah, We're Different", and I think we can all relate to a few! You can see them all here. Enjoy!
Quick anecdote: For the longest time I refused to blow a snot rocket, and then I finally did and it was like a switch was flipped - not only do I do them constantly when I'm running now, but I even catch myself about to do them in non-running situations. Wait, that's not normal?
