A large part of my job as a wealth manager is to read. I probably read eight to ten hours per day, picking up a wide variety of information along the way. I’ve decided to post some that I think you’ll find fascinating or fun. Here’s the first:
Traffic lights are thought of as red, yellow, and green. Many aren’t. Red lights are actually a mix of red and orange lights while green lights contain blue lights, too. Why?
