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.
