catching speed

I had another 1B today and I was able to get him completely done in 2 hours, plus pass off my ultrasonic PE, so I felt pretty good about my time utilization with him. It was actually my brother that came in and he's 17 years old. He drinks a ton of pop and eats plenty of treats so I decided to do my diet analysis project on him. He's supposed to be recording all the snacks he eats between meals for 3 days in a row. I think he's going to be very suprised at how many snacks he's eating and how long the acid is staying on his teeth.
