Why do you want to go to Mars?

I don’t want to move to Mars. It’s a very dangerous environment, you’d be indoors all the time or else wearing a spacesuit for short adventures outdoors. I don’t even think it’s advantageous for humans to go to Mars at all when we could just as well, and for much less expense, send our probes and robot rovers there instead. There is no good scientific reason to go to Mars.
People will go, however, because not everyone is scientifically minded.
