What Do You Floss With?

Original image

Dentally, I mean, not mentally. (Obviously you floss mentally with us, hence your reading of this blog.) But dentally-wise, it's a legitimate question -- I know when something's stuck between my teeth, the urge to get it out can be overwhelming. In such situations I rarely wait until I get to a roll of dental floss; instead I reach for whatever's available: a business card, an edge of folded paper, even the tip of a sharpened pencil has sufficed. And I know I'm not alone: a recent survey by the British Dental Health Foundation found that 60% of people picked their teeth with the nearest available toothpick-like object, "needlessly risking their dental health."
What sorts of objects? Survey respondents provided a laundry list of things most people wouldn't want in their mouths under any other circumstances, like screwdrivers, scissors, earrings, needles and knives. And it's not just the famously dentally-challenged Brits; a quick Googling reveals medical forum threads with titles like "I picked my teeth with a matchstick and a splinter jammed between them and OWWWWW," and even a (possibly fictional) story about picking one's teeth with a utility knife while driving: "I glanced at it. I was holding a utility knife. The blade fully extended. The voice in my head became clearer. It was saying 'Don't do that. Razor blades are sharp. Razor blades are not toothpicks.'" Yikes. Indeed they are not.

The alternative, however -- not picking your teeth and leaving food in there -- is also not great; according to the same finger-waving dentists who sponsored the teeth-picking survey, leaving food stuck in your teeth all day increases the likelihood of gum disease and bad breath. The only solution, it seems, is to carry floss with you.

What's the craziest thing you've flossed with?

Photo note: for all you eagle eyes out there, that's first-lady-of-California Maria Shriver, caught picking her teeth at a red light. The business card she's using belongs to "Angela Marsden, Foundation Director." That's embarrassing for both Angela and Maria -- and one reason why picking your teeth with a business card may be more dangerous than picking them with a screwdriver.

Use Wi-Fi? Your Device Is at Risk in the Latest Security Breach

Another day, another way our personal data is being compromised. This time, the latest threat to your credit card numbers, social security information, and other personal data comes from a more-than-ubiquitous source: your Wi-Fi.

As Ars Technica and The Independent report, a computer security researcher has discovered a major issue with Wi-Fi that can be used to decrypt your data. The vulnerability is the result of weakness in the WPA2 protocol that secures modern Wi-Fi networks. Hackers can steal sensitive data that has been decrypted using a method called KRACK, or Key Reinstallation Attacks. While we can't know yet if hackers have actually taken advantage of the vulnerability, its existence puts every Wi-Fi-enabled device at risk.

“If your device supports Wi-Fi, it is most likely affected,” Mathy Vanhoef, the Belgium-based researcher who discovered the exploit, said. That means your phone, your computer, and even your Wi-Fi light bulbs. The hacker only needs to be within range of your Wi-Fi—not logged into your network—to take advantage of it and steal your data. However, Ars Technica reports that Android and Linux users are more vulnerable to severe attacks than Windows or iOS users.

What should I do to protect myself?

Unfortunately, changing your passwords won’t help this time around. All you can do is wait for security updates for your devices. In the meantime, treat every Wi-Fi connection like it’s the public network at Starbucks. As in, don’t go sharing all your personal data. You can make yourself safer by using a VPN. According to cybersecurity expert Robert Graham, these kind of attacks can’t defeat VPNs.

Most companies will no doubt be releasing security patches to fix this issue ASAP, so keep a look out for any available updates.

5 Trouble-Shooting Tips to Keep Your House Plant Alive

Maybe you’ve heard that houseplants can help improve indoor air quality. Perhaps you’ve read that looking at plants can help you focus. Or maybe you just really like how that ficus looks in your living room. But buying a plant and keeping it alive are two different things, and the answer to your botanical woes isn’t always “don't forget to water it.”

Here are five green-thumb tips to make sure your plant stays as leafy green as it was the day you bought it.

1. DON’T OVER-WATER.

You don’t want to neglect your plant, but it’s easy to go overboard with the watering can, and that can be just as harmful as forgetting to water your plant for weeks. A watering schedule can help you keep track of whether or not your plants need attention, but you shouldn’t water just because it’s Sunday and that’s when you usually do it. Before you go to water your plant baby, make sure it actually needs it.

Your plant’s water needs will vary based on the type of plant, its location, how old it is, and plenty of other factors, but there are a few rules of thumb that can put you on the right track. Lift the pot. If it’s heavy, that means that the soil is full of water. If it’s light, it’s dry. Dig a finger into the soil around its roots, making sure to feel beneath the surface. Still damp? Hold off. Dry? Grab the H2O.

If you really struggle to strike the right balance between too much and too little water, consider a smart plant system. And regardless of how often you water, make sure to use a pot with good drainage to prevent root rot.

2. WATCH THE TEMPERATURE.

Be aware of where your plant is situated in the room, and whether there might be any temperature extremes there. Is your fern sitting right above the radiator? Is your peony subject to a cold draft? Is your rosemary plant stuck leaning against a window during a snowstorm?

As a rule, most houseplants can handle temperatures between 58°F and 86°F, according to a bulletin from the University of Georgia. The ideal range is between 70°F and 80°F during the day, and between 65°F and 70°F at night. Below 50°F, sensitive plants can suffer damage to their leaves. However, as with most plant advice, it depends on the species—tropical plants usually do well in higher temperatures, and some other plants are happier in colder rooms.

If your sad-looking plant is sitting in the middle of a cold draft or right next to the heater, consider moving it to a different spot, or at least a few inches away. If it’s near the window, you can also draft-proof the window.

3. MAINTAIN HUMIDITY.

Be mindful of the kind of ecosystem that your plant comes from, and know that keeping it happy means more than just finding the right amount of sun. A tropical plant like an orchid won’t thrive in dry desert air. According to the Biology Department at Kenyon College in Ohio, a dried-out plant will look faded and wilting. You can immerse it in water to help it bounce back quickly. (Warning, though: A plant that’s getting too much moisture can look that way, too.)

If your home gets dry—say, when you have the heater on full blast in the winter or the AC on constantly during the summer—you’ll need to find a way to keep your plant refreshed. Your can buy a humidifier, or create a humidity tray by placing the pot on a tray of pebbles soaked in water. The plant will soak up the humidity as the water under the pebbles evaporates. You can also get a spray bottle and mist your tropical plants periodically with water. (But don't mist your fuzzy-leafed plants.)

Not sure how humid your house is? You can get a humidity gauge (known as a hydrometer) for less than $10 on Amazon.

4. LOOK OUT FOR BUGS.

Even if you do all of the above correctly, you can still struggle to keep a plant healthy due to infestations. Keep an eye out for common pests like spider mites, which will leave brown or yellow spots on leaves or make the plant’s color dull. If you discover these tiny mites (you may need to use a magnifying glass), wash your plant immediately with water to knock off as many mites as possible. Wash the plant with an insecticidal soap, too, but make sure the label says it’s effective for mites.

5. DON’T DISCOUNT THE POT.

Healthy plants often outgrow their homes. if you notice that there are roots coming out the drainage holes at the bottom of your pot, or that water sits on the surface of the soil for a long time before draining down, or that your plant’s roots are coming up out of the soil, it’s time to upgrade to a bigger pot. Signs of a “root bound” plant whose root system is too big for its container can also include wilting, yellowed leaves, and stunted plant growth.

No matter what the size of your plant, it’s good to repot it once in a while, since the nutrients in the soil deplete over time. Repotting creates a fresh nutritional start and can help perk up unhappy plants.

If your plant looks unhealthy and you're still stumped, try consulting the website of a university horticulture department for other signs of plant distress and potential solutions.
