A: "Hi Mike. What have you been up to?"

B: "Not much. I started exercising."

A: "Trying to get in shape?"

B: "Yeah, and I need to start improving my health."

A: "Me too. What are you doing besides exercising?"

B: "That's about all."

A: "I think if you eat better, it will help tremendously."

B: "Sleep is good too. I heard people who sleep an average of eight hours a day have less health problems."

A: "Looks like there are a lot of things to do to stay healthy."

B: "True. But I think it is worth it. When you get old, you want to be healthy and active."
