F:     Can you imagine being a tour guide in space? That sounds so cool.

M:   I don't know. It seems like you’dwork long hours.

F:     Why's that?

M:   Think about it: it takes two or three days to fly to the moon. Imagine being on a plane that long.

F:     Hmmm … good point.

M:   And traveling in space isn't easy; it's really hard on the body.

F:     Yeah well, I still think it's a cool job.

M:   It sounds cool, but I bet it won't be an easy job at all.

F:     Ugh, listen to this job: bioengineer. They make new body parts for people. 

M:   Interesting.

F:     Really? I think it sounds kind of gross.

M:   Yeah, but think about people in car accidents … and older people. In the future, bioengineers will help them live longer, healthier lives.

F:     Yeah, that's true. But bioengineers won't just help these kinds of people.

M:   What do you mean?

F:     You know, maybe someday, healthy people will go to bioengineers to change their body so it's better in some way — so they’re stronger, faster, or better looking. 

M:    Yeah, probably, but I think that's a good thing. 

F:      I don't know. I think it’s kind of weird.
