As we sat sipping coconut broth mixed with rice, I looked up and noticed three couples enter the restaurant, waiting for the hostess to return from the kitchen to seat them.
I'm a naturally observant person, and I tend to stare at people without really caring if it makes them uncomfortable.
We generally look a lot less attractive after skimping on sleep.
In 2010, researchers took photos of people who'd slept for at least eight hours the night before and people who hadn't slept in 31 hours.
Not only were the sleep-deprived people perceived as more tired (obviously), but they were also perceived as less attractive, less healthy, and sadder. For a 2014 Chinese study, researchers had men and women look at photos of other people, all displaying neutral expressions.
I just mean these ladies were normal, pretty women, and their partners were so very on the opposite side of the spectrum.
I pointed out this realization to my sister and asked if she was as unsurprised by it as I was.
Some of those photos were accompanied by the Chinese words for "decent" and honest"; the others were accompanied by the Chinese words for "evil" and "mean"; still others weren't accompanied by any information.
Participants ended up rating people least attractive when they were described as evil and mean.
