Try Your Hand at the Bridge and Torch Problem

There are a large number of “river crossing puzzles” in the world of logic puzzles, in which people must cross a river with a variety of constraints. One of the most popular of these puzzles is the Bridge and Torch Problem, which tests your logic skills and your rational thinking. Though it may seem like a simple enough question, the answer to this tricky word problem eludes many of the people who try to solve it.

In the Bridge and Torch Problem, four people approach a riverbank at night. The narrow bridge nearby can only hold two people at a time. They only have one torch, but it has to be used when crossing the bridge. It takes Person A one minute to cross, Person B two minutes to cross, Person C five minutes, and Person D eight minutes. Two people crossing the bridge together must move at the slower person’s pace.

Can all of the people cross the bridge in 15 minutes or less? Once you reach an answer, check it here!

Did You Know These Cool Facts About Tea?

There are few things more relaxing than kicking back after a long day with a hot mug of tea, but how much do you really know about the brew that you’re sipping? From its numerous health benefits to its rich, global history, there’s a whole lot to learn about this fascinating beverage!

  • Tea bags were originally designed in the early 1800s. They were created to hold samples of tea brought to America from India. Today, tea bags are much more commonly used than loose-leaf varieties.
  • Darjeeling tea is the world’s rarest tea. It gets its name because it's grown in the Indian region of Darjeeling. While many types of teas are labeled Darjeeling, only 1/4 are actually from the region!
  • While tea styles like black, green, white, and oolong taste very distinct, they all come from the same Camellia sinensis plant. It's the way the leaves are harvested and treated that determines their color and variety.
  • Herbal teas are not really teas at all. Rather, they're infused fruits, flowers, plants, and herbs.
  • China is the world’s largest tea producer. The country supplies 29% of the tea in the world. India comes in a close second.
  • The Chinese are not the world’s largest tea consumers. That title belongs to the United Arab Emirates!

How to Help Ensure Your Growing Teen Is Getting the Proper Nutrition

Teenagers may seem like they don’t need your help with anything, but as a parent, you know that this simply isn’t true. When it comes to proper nutrition, your growing teen needs you more than ever. Here are a few smart tips to help ensure that your teenager is eating the right foods and maintaining a healthy lifestyle.

  1. Have regular meals together. Eating together doesn’t just bring you closer as a family, it also ensures that your son or daughter eats a well-balanced dinner every evening. Prepare meals with lots of whole grains, lean meats and fish, and fresh vegetables.
  2. Prepare more food. As your child becomes a teenager, his or her appetite will begin to increase dramatically. Keep teens energized by serving larger portions at mealtime and keeping lots of healthy snacks on hand.
  3. Limit saturated fats and sugars. Even if your teen loves to snack on potato chips and chocolate candies, these things can contribute to certain diseases later in life. Try to limit the foods that contain saturated fats, sugars, and sodium in your household.
  4. Increase calcium intake. Because teenagers typically go through growth spurts, they require much more calcium than children and adults. Serve low fat milks, yogurt, or even calcium supplements. Ask your child's doctor for advice.

What to Keep in Mind When Counting Calories

You know that counting calories is essential when it comes to losing weight, but do you really understand exactly what calories are? Here are a few things that you should understand about your caloric intake.

  1. Know the definition. A calorie is a term used to describe how much energy there is in a food. Your body needs a certain amount of calories to function, but excess calories turn into fat.
  2. Know your limit. Everyone has a different daily calorie limit, and it all depends on your sex, age, height, and weight. You’ll need to visit a doctor or find a chart online to determine your personal recommended daily intake.
  3. Create a calorie log. Keep track of how many calories you consume by recording your meals in a daily diary.
  4. Evenly distribute calories. Plan ahead of time so that you can split up your calories between each meal of the day. Be careful not to consume the majority of your calories in the morning, because you won’t have many remaining to "spend" on dinner.
  5. Beware of beverages. Many people don’t realize it, but the calories in drinks can really take a toll on your daily calorie limit. Be careful to record all of the beverages that you consume in addition to your meals.

How to Fight Insomnia and Get a Better Night’s Sleep

If you spend most nights tossing and turning for hours, you likely spend your days feeling tired, irritable, and unable to concentrate. Insomnia affects more people than you might think, but these proven tips can help you get a good night’s sleep.

  1. Set a schedule. If you often go to bed at very different times, it could be a cause of your insomnia. Try to set a bedtime for yourself and stick to it so that your body gets used to falling asleep at the same time each night.
  2. Give yourself 15 minutes. If you can’t fall asleep within 15 minutes of going to bed, get up and do something else. Lying awake for hours could cause you to stress out more, so try to tire yourself out by reading or washing the dishes.
  3. Change your diet. Don’t eat right before you go to bed, but try not to go to bed hungry, either. You likely already know that you shouldn’t drink caffeine before bedtime, but try to avoid alcohol, as well.
  4. Create a comfortable sleep space. If you still have trouble sleeping, it may be your surroundings. Wear earplugs if the outside noise is too loud, replace your blankets to suit your temperature needs, or add a mattress pad if your bed is uncomfortable.

4 Health Benefits of Napping

While you may think of napping as a luxury reserved for the weekends, taking quick power naps throughout the workweek is not without its benefits — just make sure your boss is okay with it first! Here are four of the most important health benefits of napping:

1) It increases your level of alertness.
Even a 40-minute nap will increase how alert you are by a full 100 percent. Just think of the ways that extra energy will improve your work performance or help you tackle chores around the home!

2) It boosts memory retention.
If you take a mid-afternoon nap when you start to feel tired, once you wake up you’ll be able to remember more facts and deliver a better performance without feeling sluggish.

3) It prevents disease.
That’s right: napping regularly not only improves your brain function, it also improves your overall health. Napping for just 30 minutes a day a few times a week is said to decrease your risk of heart disease and diabetes and help your body to heal itself more quickly.

4) It makes you happier.
It may seem like common sense that you feel less grumpy after a nap, but there’s more to it than that. Napping increases your brain’s production of the mood-enhancing neurotransmitter serotonin, which increases overall feelings of well-being and decreases stress.

How to Help Preserve the Health of Your Eyes

You lift weights for your muscles and use fancy creams for your skin, but what do you do to protect your eyes? The eyes are often overlooked, but they are some of the most important parts of the body. Here are a few simple things that you can do to help ensure good eye health for years to come.

  1. Have a comprehensive exam. If you don’t wear glasses or contacts, you might go for years between eye exams. The only real way to know how healthy your eyes are is by having a comprehensive dilated exam administered by an eye care professional, so be sure to schedule an appointment.
  2. Eat the right foods. Yes, it’s common knowledge that carrots are good for your eyes, but other foods that can help improve the health of your eyes, as well. Dark, leafy vegetables, fruits, and fish high in omega-3 fatty acids have all been linked to improving eye health.
  3. Keep them protected. Sunglasses don’t just look cool, they also serve a very important purpose. Wearing sunglasses helps to shield your eyes from the harmful UV rays from the sun, so be sure to choose ones that block 99 to 100 percent of UVA and UVB radiation.

The Essentials Every Home First Aid Kit Should Contain

Accidents happen. Any given day could present you with slips, scrapes, burns, and bruises, which is why a first aid kit is something every home should have within easy reach. Here are a few essentials that every home first aid kit should contain.

  1. Adhesive bandages. Most people have the traditional bandage strips on hand, but make sure to stock up on larger and smaller types for cuts of different sizes and for awkward locations.
  2. Tweezers. You’ll never know the importance of owning tweezers until to rub your foot against the rough wood on a deck or patio. Ouch!
  3. Thermometer. If you’re worried that you might be running a fever, a reliable thermometer can tell you for sure. If you have children, be sure to invest in a children’s thermometer, as well.
  4. Aspirin. From soothing a headache to relieving aching muscles, aspirin is a necessity for all kinds of ailments. Once again, children need their own type of aspirin, so stay well-stocked on both types if you share your home with little ones.
  5. Topical antiseptic. To reduce the risk of infection, clean any small cuts with topical antiseptic or antiseptic wipes.

Are You Brushing Your Teeth Correctly? Find Out Here!

You’ve brushed your teeth for as long as you can remember, but how can you be sure that you’re doing it correctly? Check out these simple steps for proper tooth brushing to find out.

  1. Twice a day is only the beginning. Although many people are taught to brush their teeth in the morning and the evening, that’s actually only the minimum amount. Brushing your teeth after a large meal or any time you drink a potentially staining beverage is always a good idea.
  2. Brush in a circular motion. Dentists recommend brushing in a circular motion up toward the gums rather than the usual back and forth motion across the teeth. This technique removes bacteria without causing gum pain.
  3. Stop the final rinse. While many people rinse their mouths out with a bit of water after brushing, this is harmful because it removes the beneficial film delivered from the toothpaste. If you feel the need to rinse, only put a small amount of water in your mouth and swish it across your tongue rather than around your teeth and gums.
  4. Don’t skimp on flossing. Flossing is just as important as brushing, and it should be done almost as often. Bonus points if you floss before brushing, as that enables the toothpaste to coat those hard-to-reach places between the teeth.
