In his Book of Problems, Aristotle asked, “Why is it that one sneezes more after one has looked at the sun?” It’s known as the photic sneeze reflex!

What does it mean to be color blind? It’s a question many people ask. “Color blind” doesn’t necessarily mean you only see shades of gray. In fact, it is extremely rare to be truly color blind (that is, you see only black and white).
