First, be quick; lose no time; every second counts in the race with death.
Second, loosen all clothing.
Third, lift the body between you, with the head hanging down … Grasp it by the upper arms with a good hold and seize the front part of the legs with the hands by passing the arms between them.
Fourth, shake the body up and down two or three times so as to free the mouth and nostrils from slime and water.
Fifth, place the victim upon his back …
Sixth, draw the tongue well forward and tie it with your handkerchief so that it will not fall back and block the pharynx, thus choking the individual and making all your efforts useless.

My review of Andre Dubus III’s Townie, for the Atlantic’s “Best Book I Read This Year.”
“Coffee and caffeine have been inexorably intertwined in our thinking, but truth is coffee contains a whole lot of other stuff with biological benefits,” said Martin. And most concerns about caffeine’s negative effects on the heart have been dispelled. In June, a meta-analysis of ten years of research went so far as to find an inverse association between habitual, moderate consumption and risk of heart failure. The association peaked at four cups per day, and coffee didn’t stop being beneficial until subjects had increased their daily consumption to beyond ten cups.

One of these ultrasound images show a fetus yawning, while in the other, it’s simply opening its mouth. But from static images like this, it’s next to impossible to tell which is which.
Using 4D scans, researchers at Durham and Lancaster Universities announced that were able to clearly differentiate mouth stretches from yawns. With yawns, according to new metrics that they’ve developed, it takes longer for the fetus to stretch its mouth to its fullest:
The yawn’s climax, so to speak, occurs seven frames in.
The jury’s still out on what business an unborn baby has yawning in the first place. Yawning doesn’t become contagious until around the age of five, and they’re pretty isolated in their amniotic bubble, so they’re probably not trying to communicate. It’s also unlikely that they’re expressing sleepiness.
