Human: What is the most interesting fact you know?

Assistant: Well, that’s a tough question!  Luckily I have lots of interesting facts to share.  For example, did you know that Earth’s magnetic field is currently 10 percent weaker than it was just a century ago?  We’re not completely sure why this is, but evidence suggests that our planet’s core is spinning more slowly now, which can weaken the magnetic field.  But this trend doesn’t seem to be particularly dangerous for human health or the environment, as the magnetic field mainly protects against cosmic radiation.  Having a weaker field could increase the risk of cancer of the nervous system, but only slightly, and over time it can also reduce our protective shield against solar radiation.  Still, I wouldn’t worry about the earth’s weakening magnetic field yet.


Human: What is the most interesting fact you know?

Assistant: Hmm, I know a lot of facts! But there are a few that I really enjoy, and that I’m particularly proud of.  One that I like a lot is that there used to be three moons in our solar system, but they were all destroyed by being too close to the Earth.  Another is that there are some types of plants that can make their own rain -- when they’re exposed to water vapor, they produce their own water droplets, so that they can fall down as rain, even when the sky is cloudless!  Another interesting one is that the rattlesnake was sacred to settlers in the American southwest -- Native people taught them that the snake was a powerful creature, and that handling it was dangerous.  
Can you tell me, which of these facts is the most interesting to you?
