Where do freckles come from?
From the sun? Or is it genetic?
Are people born with them? If so, did some relative way back get freckles? Then it went into the DNA?

We were talking about the Chicago marahon at school, and my science teacher says that the misting stations located throughout the marathon are there so that your body does not need to produce as much sweat and can take water directly through your pores. But my mom who is a doctor says that can't happen. Who is right?
