I learned to have some hope still in our country's political systems. They're still definitely flawed, but they no longer seem impossibly broken. - anonymous

The more I learn about how the human body works, the more amazed I am. We're such complicated, finely tuned creatures! Dozens of systems all working together unseen (most of the time) to keep us breathing. Amazing! - anonymous

Getting out of one’s comfort zone and being amazed by friendly strangers that make you feel like you’re with people whom you’re friends with. - anonymous

The American Ornithological Society uses a system of four-letter codes for every species of bird in North America. It's usually the first four letters of the common name (MALL for Mallard), or the first two of each word if the common name has two words (NOMO for Northern Mockingbird), etc. This is called the Alpha Bird Banding Code! I discovered this because a recent update means that the Great Egret has now been divided into two separate species, American Egret in the Western Hemisphere and Great White Egret in the Eastern Hemisphere. Which means GREG has been replaced by AMEG and GWEG. - anonymous

Sea otters hold hands while sleeping on their backs in the water to keep from drifting apart. - anonymous
