Lactic Acid

Zoey learns a lot of interesting things from the show and books The Magic School Bus. One thing she learned was about lactic acid making muscles tired. She was riding bikes with a neighbor boy, and I was pathetically trying to keep up with them while running (it is hard to race two kids who are racing each other on bikes, let me tell you... I admit defeat!) Anyway, the boy, Jaden, slowed down and said, "Let's take a break, my legs are tired." Zoey replies, "Oh, you got lactic acid in your legs?" I was cracking up!! Jaden just looked at her all confused, and said, "Uh, no?" And she said, "Yes, you do!" and took off... She won that lap!!
