I think I'll actually contribute afterall...
After finishing a tempo run the other day on a measured gravel path, I started to head back home, and saw a group of high school kids grouped near the entrance to the trail back to my house. There were 4-5 boys and 3-4 girls. It was absurdly hot; I had barely made it through the tempo run, even at a reduced pace. It was still another 3 miles plus back to my house, so I took a shot in the dark and asked the kids if any of them had any water. They all shook their heads or said they didn't have any, but one girl put her hands on her hips and said, "I don't have any water, but I've got something else wet for you!"
I said, "I get that somewhere else, but thanks for the offer!" and ran home thirsty, with cotton mouth, and an increased understanding of how singers like Katy Perry can be commercially successful.
