I totally agree with Mika S. It was easy to understand but because they chose this way to explain the state of Genpatsu, I just couldn't take the video seriously. I thought the video was frivolous, and I also think the problem of genpatsu is much more serious. I think the video was simple and easy for the kids to understand but they missed out few important points that kids also should understand.
I don't know why the Japanese explained it in this way. Dr.Armstrong said that Americans never relate anything to poop but how would you explain the state of genpatsu instead of relating it to poop like the video? If you can't think of anything, maybe the idea of using poop is the best way to explain. Therefore, there will be no cultural difference of talking about poop.
