What have you been up to?"

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."
