Take Tulsi

Research suggests that this Ayurvedic herb, also called holy basil, may help manage levels of the stress hormone cortisol, helping to boost your mood. Look for teas and supplements in health-food stores and follow package directions.

Benifits of Bananas

People whose diets are rich in potassium may be less prone to high blood pressure. Besides reducing sodium and taking other heart-healthy steps, eat potassium-packed picks such as bananas, cantaloupe, and oranges.

Go Fish

If you suffer from dry eyes, up your seafood intake. Salmon, sardines, and mackerel contain omega-3 fatty acids, which the body uses to produce tears, among other things. Research suggests that people who consume higher amounts of these fats are less likely to have dry eyes.

Sniff Rosemary

According to some research, catching a whiff of this aromatic herb may increase alertness and improve memory. To stay sharp, try smelling fresh rosemary or inhaling the scent of rosemary essential oil before a test or meeting.

Enjoy Ginger

The volatile oils in ginger have long made it a useful herbal remedy for nasal and chest congestion. Pour 2 cups of boiling water over a 1-inch piece of peeled, grated ginger; steep for 10 minutes; and strain. Add a pinch or two of cayenne pepper to the water and drink as needed.

Rub Your Temples

Tame tension headaches by rubbing peppermint oil, Tiger Balm, or white flower oil into your temples. All three remedies contain menthol, which has analgesic properties

Go Herbal

For varicose veins, try horse chestnut, an herbal extract that's been shown in studies to strengthen veins and reduce swelling. The herb is also available in topical creams, though there's not as much evidence for these.

Sip Oolong Tea

Research suggests that people with mild eczema who drink oolong tea three times a day may show improvement in itching and other symptoms. Compounds in the tea called polyphenols appear to be responsible.

The total weight of all the ants on Earth is about the same as the weight of all the humans on earth.

Unless you leave food out and attract them, humans rarely have a need to think about ants. They're tiny, not poisonous and not particularly terrifying, like say, spiders. However, they far outnumber humans on earth--by one million to one!

Funnily enough, they are also roughly a millionth of a human in size too. Do the math--the total weight of all the ants on earth matches the total weight of the entire human population.

There are 10,000 different types of ants and they've been around for a long time. Ancients ants have been discovered in fossilized sap from 100 million years ago!

Over time, ants have changed very little. Their way of life and survival is successful. Some scientists attribute this to their unselfish ways. Ants live in colonies and bring their prey back to their many relatives to share.

Grapes EXPLODE when you put them in the microwave!

You may have heard of frozen grapes as a tasty snack, but what about heating grapes in the microwave? You probably shouldn't try this one. It turns out that grapes react very oddly when they're microwaved.

Since grapes are full of moisture, when they are microwaved, that moisture turns to steam. If the stem is still attached to the grape and there is nowhere for the steam to escape, it will explode slightly and rupture the skin.

If you place two grapes close together with their stem holes facing each other, some arcing and sparking will occur. If there is just a single grape with its stem hole open, it will let out a stream of steam. Good thing we don't serve grapes warm.

In Japan they have square watermelons.

They get square watermelons by growing them inside of square glass cases. That way they can fit easily into an overcrowded refrigerator, and you can stack things on them.

Square watermelons are expensive though (10,000 yen or about $82). Compare that to regular round watermelons which cost about $15-20 in Japan.

The square boxes they're grown in are the exact dimensions of Japanese refrigerators, which means they fit perfectly. At $82 each, these square watermelons probably wouldn't be too popular in the United States. Our solution for a lack of refrigerator space? Smaller, seedless watermelons.
