Come with me so that I can show you some new and healthy things since 1975.
By the time tunnel.
Where do you come from?

Hey, what are those?
What are they used for?
Why do people here recycle used paper?
I see.
Hey, look. That must be the newest radio!
Hmm, a mobile phone?
Why are people doing exercise here?
Alright! Then I don't need to wear tight shirt to look slim now. Let's go and e-x-e-r-c-i-s-e!
Don't worry, buddy. I will remember that. Thanks for the trip. I've learnt a lot of healthy things. It's time for me to go back to 1975.
Bye, Andy.
Welcome to the present day. I will be your guide to the city. You can ask me any questions you want to learn about the new things you will see today.
They are recycle bins.
They are used for collecting used paper for recycling.
We recycle used paper so we don't need to cut so many trees.
No, this is a mobile phone!
The mobile phone is another great invention in the 21st century. It has become popular since 1993. It is small and convenient to carry. Nowadays, if you want to call someone on the street, you don't have to look everywhere for a phone box.
People started to care about their bodies in the 1990s. Since then, they go to gyms more often because exercise can help to burn body fats.
Doing exercise can give you a strong body but it will not make you a healthy person unless you give up unhealthy habits like smoking and overeating.
Ok, Tony. Go in the time tunnel.
