M: (23)The number of overweight children in this nation is on the rise, more than doubling since 1980s. Magazine editor in chief, Denise Broody is here today. Hi, Denise, how are you?
W: Hi, I am happy to be here.
M: (24)Now, toy makers are creating new toys to get kids off the couch and moving in fitness. I know you are with the top 10 toys that the magazine has chosen.
W: Yes, that’s right.
M: How did you pick these, or how did you raise them?
W: Well, we want to try and find toys that are safe and smart, that can get kids going, and that are fun to the whole family, so that you can emphasize, kids and mum can do the things together with dad.
M: There is no question we want to get them more active. Let’s try on this new kids running machine.
W: (25)This is a great running machine, because you put it right next to your kid and you can exercise at the same time. So you can see how the kid can really run out of some energy there. Calories are really important and it’s safe, because it starts and stops when the kid starts and stops, so that’s very different than an adult running machine which can be dangerous for the little guys.
M: Right.
W: And it’s interactive, which might encourage them. We’re trying to help our children to get in better shape. We’ll do everything we can.
M: All right, we are about to run out of the time, but it’s needful. Thanks so much.
