On: Brain size drives differences in yawn duration across mammals and birds

[amarant]

I'm definitely citing this study next time I'm sleepy and someone comments on my constant yawning

[purplecats → amarant]

title doesn't state if larger size is positively correlated with more frequent yawns :)

[airstrike → purplecats]

You're giving people far more credit than I would! You can get a ton of mileage out of the most spurious of correlations...
