Five Things #227

Christiania, Copenhagen — September 2015

This week’s Five Things…

1. “Happiness & sadness are contagious, this study finds. Each person in your network who became happy increases your chance of becoming happy by 9%, an unhappy person drops it by 7%. If a friend who lives within a mile becomes happy, your chance of becoming happy goes up 25%.”

2. A very good explainer of hypnic jerks. A thing I have regularly experienced but not known the name of!

3. Not just any illusion, an award-winning illusion.

4. A fascinating episode of Lexicon Valley on how new words are formed from older ones, and how their meanings drift over time.

5. I didn’t have Sea Shanty’s down as a 2021 trend.
