The British epidemiologist Jeremy N. Morris died recently. In the 1940s and 1950s, Morris did some of the first empirical research that showed how important it is, health-wise, to have a job that involves some physical activity. A 1949 study compared the health of the drivers of London’s double-decker buses with that of the conductors.“And there was a striking difference in the heart-attack rate. The drivers of these double-decker buses had substantially more, age for age, than the conductors.” The data were so telling because drivers and conductors were men of much the same social class. There was only one obvious difference between them. “The drivers were prototypically sedentary,” explains Morris, “and the conductors were unavoidably active. We spent many hours sitting on the buses watching the number of stairs they climbed.” The conductors ascended and descended 500 to 750 steps per working day. And they were half as likely as the drivers to drop dead of a sudden heart attack.The idea that exercise is good doesn’t seem particularly revolutionary today. But the thing is, this “information economy” hasn’t been conducive to jobs that require you to break a sweat (or move at all, really, save your typing fingers). We seem to be moving towards more sedentary work. With unemployment at 10.2 percent, providing jobs of any stripe is tough right now, but we should also consider how to provide employment that doesn’t leave people prone to heart attacks. And if we can do it without resorting to the treadmill desk, that’d be great.[youtube]https://www.youtube.com/watch?v=CPjN07JyVjoVia WSJ health blog. Photo from Flickr user Salim Virgi (cc).

Man’s dog suddenly becomes protective of his wife, Internet clocks the reason right away
The online community came through in a big way.
Reddit user Girlfriendhatesmefor’s three-year-old pitbull, Otis, had recently become overprotective of his wife. So he asked the online community if they knew what might be wrong with the dog.
“A week or two ago, my wife got some sort of stomach bug,” the Reddit user wrote under the subreddit /r/dogs. “She was really nauseous and ill for about a week. Otis is very in tune with her emotions (we once got in a fight and she was upset, I swear he was staring daggers at me lol) and during this time didn’t even want to leave her to go on walks. We thought it was adorable!”
His wife soon felt better, butthe dog’s behavior didn’t change.
Otis knew before they did. Canva Girlfriendhatesmefor began to fear that Otis’ behavior may be an early sign of an aggression issue or an indication that the dog was hurt or sick.
So he threw a question out to fellow Reddit users: “Has anyone else’s dog suddenly developed attachment/aggression issues? Any and all advice appreciated, even if it’s that we’re being paranoid!”
The most popular response to his thread was by ZZBC.
Any chance your wife is pregnant?

The potential news hit Girlfriendhatesmefor like a ton of bricks. A few days later, Girlfriendhatesmefor posted an update and ZZBC was right!
“The wifey is pregnant!” the father-to-be wrote. “Otis is still being overprotective but it all makes sense now! Thanks for all the advice and kind words! Sorry for the delayed reply, I didn’t check back until just now!”
Redditors responded with similar experiences.
Anecdotal I know but I swear my dog knew I was pregnant before I was. He was super clingy (more than normal) and was always resting his head on my belly.

So why do dogs get overprotective when someone is pregnant?
Jeff Werber, PhD, president and chief veterinarian of the Century Veterinary Group in Los Angeles, told Health.com that “dogs can also smell the hormonal changes going on in a woman’s body at that time.” He added the dog may “not understand that this new scent of your skin and breath is caused by a developing baby, but they will know that something is different with you—which might cause them to be more curious or attentive.”
The big lesson here is to listen to your pets and to ask questions when their behavior abruptly changes. They may be trying to tell you something, and the news may be life-changing.

Why mass shootings spawn conspiracy theories
Mass shootings and conspiracy theories have a long history.
While conspiracy theories are not limited to any topic, there is one type of event that seems particularly likely to spark them: mass shootings, typically defined as attacks in which a shooter kills at least four other people.
When one person kills many others in a single incident, particularly when it seems random, people naturally seek out answers for why the tragedy happened. After all, if a mass shooting is random, anyone can be a target.
Pointing to some nefarious plan by a powerful group – such as the government – can be more comforting than the idea that the attack was the result of a disturbed or mentally ill individual who obtained a firearm legally.
