Why Can't Dogs Eat Chocolate?

Even if you don’t have a dog, you probably know that they can’t eat chocolate; it’s one of the most well-known toxic substances for canines (and felines, for that matter). But just what is it about chocolate that is so toxic to dogs? Why can't dogs eat chocolate when we eat it all the time without incident?

It comes down to theobromine, a chemical in chocolate that humans can metabolize easily, but dogs cannot. “They just can’t break it down as fast as humans and so therefore, when they consume it, it can cause illness,” Mike Topper, president of the American Veterinary Medical Association, tells Mental Floss.

The toxic effects of this slow metabolization can range from a mild upset stomach to seizures, heart failure, and even death. If your dog does eat chocolate, they may get thirsty, have diarrhea, and become hyperactive and shaky. If things get really bad, that hyperactivity could turn into seizures, and they could develop an arrhythmia and have a heart attack.

While cats are even more sensitive to theobromine, they’re less likely to eat chocolate in the first place. They’re much more picky eaters, and some research has found that they can’t taste sweetness. Dogs, on the other hand, are much more likely to sit at your feet with those big, mournful eyes begging for a taste of whatever you're eating, including chocolate. (They've also been known to just swipe it off the counter when you’re not looking.)

If your dog gets a hold of your favorite candy bar, it’s best to get them to the vet within two hours. The theobromine is metabolized slowly, “therefore, if we can get it out of the stomach there will be less there to metabolize,” Topper says. Your vet might be able to induce vomiting and give your dog activated charcoal to block the absorption of the theobromine. Intravenous fluids can also help flush it out of your dog’s system before it becomes lethal.

The toxicity varies based on what kind of chocolate it is (milk chocolate has a lower dose of theobromine than dark chocolate, and baking chocolate has an especially concentrated dose), the size of your dog, and whether or not the dog has preexisting health problems, like kidney or heart issues. While any dog is going to get sick, a small, old, or unhealthy dog won't be able to handle the toxic effects as well as a large, young, healthy dog could. “A Great Dane who eats two Hershey’s kisses may not have the same [reaction] that a miniature Chihuahua that eats four Hershey’s kisses has,” Topper explains. The former might only get diarrhea, while the latter probably needs veterinary attention.

Even if you have a big dog, you shouldn’t just play it by ear, though. PetMD has a handy calculator to see just what risk levels your dog faces if he or she eats chocolate, based on the dog’s size and the amount eaten. But if your dog has already ingested chocolate, petMD shouldn’t be your go-to source. Call your vet's office, where they are already familiar with your dog’s size, age, and condition. They can give you the best advice on how toxic the dose might be and how urgent the situation is.

So if your dog eats chocolate, you’re better off paying a few hundred dollars at the vet to make your dog puke than waiting until it’s too late.

Why Do Supreme Court Justices Serve for Life?

There are few political appointments quite as important as a nomination to the U.S. Supreme Court. Unlike a cabinet secretary or an ambassador, justices serve for life. In the modern era, that often means more than three decades on the court—thanks to increased lifespans, justices appointed in the next century are expected to sit on the Supreme Court for an average of 35 years, compared to the average of around 16 years that judges served in the past. Because of this shift, some scholars have begun to question whether lifetime appointments are still appropriate, as the definition of “for life” has changed so much since the constitution was written. But why do justices serve for life, anyway?

Well, for one thing, the U.S. Constitution doesn’t exactly specify that justices and the court are in a “’til death do us part” relationship. Article III says that judges (of both the Supreme Court and lower federal courts) “shall hold their offices during good behavior.” So technically, a judge could be removed if they no longer meet the “good behavior” part of the clause, but there are otherwise no limits on their term. In practice, this means they have their seat for life, unless they are impeached and removed by Congress. Only 15 federal judges in U.S. history have ever been impeached by Congress—all lower court judges—and only eight have been removed from office, though some have resigned before their inevitable removal.

The only Supreme Court justice Congress has tried to impeach was Samuel Chase, who was appointed by George Washington in 1796. Chase was an openly partisan Federalist vehemently opposed to Thomas Jefferson’s Democratic-Republican policies, and he wasn’t afraid to say so, either in his role as a lower court judge or once he was appointed to the Supreme Court. In 1804, the House of Representatives, at then-president Jefferson’s urging, voted to impeach Chase, accusing him, among other things, of promoting his political views from the bench instead of ruling as a non-partisan judge. However, he was acquitted of all counts in the Senate, and went on to serve as a Supreme Court justice until his death in 1811.

The point of giving justices a seat on the bench for the rest of their lives (or, more commonly nowadays, until they decide to retire) is to shield the nation’s highest court from the kind of partisan fighting the Chase impeachment exemplified. The Supreme Court acts as a check against the power of Congress and the president. The lifetime appointment is designed to ensure that the justices are insulated from political pressure and that the court can serve as a truly independent branch of government.

Justices can’t be fired if they make unpopular decisions, in theory allowing them to focus on the law rather than politics. Justices might be nominated because a president sees them as a political or ideological ally, but once they’re on the bench, they can’t be recalled, even if their ideology shifts. Some data, for instance, suggests that many justices actually drift leftward as they age, no doubt infuriating the conservative presidents that appointed them.

The lack of term limits “is the best expedient which can be devised in any government, to secure a steady, upright and impartial administration of the laws,” Alexander Hamilton wrote in the Federalist No. 78. The judiciary, he believed, “is in continual jeopardy of being overpowered, awed, or influenced by its coordinate branches,” and “nothing can contribute so much to its firmness and independence, as permanency in office.” Without lifetime job security, he argued, judges might feel obligated to bow to the wishes of the president, Congress, or the public, rather than confining their work strictly to questions of the Constitution.

While lifetime appointments may be a longstanding tradition in the U.S., this approach isn’t the norm in other countries. Most other democracies in the world have mandatory retirement ages if not hard-and-fast term limits for high court judges. UK Supreme Court justices face mandatory retirement at age 70 (or 75 if they were appointed before 1995), as do judges on Australia’s High Court. Canadian Supreme Court justices have a mandatory retirement age of 75, while the 31 justices of India’s Supreme Court must retire by the age of 65. Meanwhile, the oldest justice now on the U.S. Supreme Court, Ruth Bader Ginsburg, is currently 85 and kicking. Oliver Wendell Holmes Jr., the oldest justice in U.S. history, retired in 1932 at age 90.

Though the U.S. Supreme Court has never had term limits before, there have recently been serious proposals to implement them. Term limits, advocates argue, could combat partisan imbalances on the court. Presidents wouldn’t get to appoint justices purely based on whether someone died while they were in office, and the stakes for political parties nominating a justice would be slightly lower, possibly leading presidents and Congress to compromise more on appointments. One popular suggestion among political analysts and scholars is to impose an 18-year term limit, though critics note that that particular plan does bring up the potential that at some point, a single president could end up appointing the majority of the justices on the court.

In any case, considering such a change would likely require a constitutional amendment, which means it’s probably not going to happen anytime soon. For the foreseeable future, being on the Supreme Court will continue to be a lifetime commitment.

How Often Should You Poop?

When it comes to No. 2, plenty of people aren’t really sure what’s normal. Are you supposed to go every day? What if you go 10 times a day? Is that a sign that you’re dying? What about once every three days? Short of asking everyone you know for their personal poop statistics, how do you know how often you’re supposed to hit the head?

Everyone’s system is a little different, and according to experts, regularity is more important than how often you do the deed. Though some lucky people might think of having a bowel movement as an integral part of their morning routine, most people don’t poop every day, as Lifehacker informs us. In fact, if you go anywhere between three times a day and three times a week, you’re within the normal range.

It’s when things change that you need to pay attention. If you typically go twice a day and you suddenly find yourself becoming a once-every-three-days person, something is wrong. The same thing goes if you normally go once every few days but suddenly start running to the toilet every day.

There are a number of factors that can influence how often you go, including your travel schedule, your medications, your exercise routine, your coffee habit, your stress levels, your hangover, and, of course, your diet. (You should be eating at least 25 to 30 grams of fiber a day, a goal that most Americans fall significantly short of.)

If you do experience a sudden change in how often you take a seat on the porcelain throne, you should probably see a doctor. It could be something serious, like celiac disease, cancer, or inflammatory bowel disease. Or perhaps you just need to eat a lot more kale. Only a doctor can tell you.

However, if you do have trouble going, please, don’t spend your whole day sitting on the toilet. It’s terrible for your butt. You shouldn’t spend more than 10 to 15 minutes on the toilet, as one expert told Men’s Health, or you’ll probably give yourself hemorrhoids.

But if you have a steady routine of pooping three times a day, by all means, keep doing what you’re doing. Just maybe get yourself a bidet.
