Would you like to live on Mars, Sandy?
I'm not sure if it's worth the risk. It worries me. Why? It would be quite safe. After all, humans have already been to the Moon. Maybe you're right, but we might get ill from living there. I don't think so, Sandy. It's just a different kind of life. It would be great to live on another planet. What about all your friends here on the Earth if you go to Mars? I want you all to come too. OK. If we all go together, it should be fun.
