Eyepatches can help you see in the dark.

Here’s how it works:

You wear an eyepatch over one eye all day whenever you are out in the sun or in a well-lit area. The eyepatch should always be over the same eye whenever you are in the light. Then, whenever it’s dark, switch the eyepatch to the other eye. Your eyes take time to adjust to different light conditions. If one eye is only ever exposed to darkness, and the other one only ever exposed to light, your eyes will never have to adjust. Switching from day-vision to night-vision is as easy as switching your eyepatch to a different eye.

It has been speculated that pirates wore their trademark eyepatches to make it easier to transition from being above deck on a ship to going below deck where it’s darker. Of course, eyepatches have many uses, from covering up injuries, to treating “lazy eye”. For all we know, a lot of pirates could have had lazy eye.

Warmer climates result in more baby girls.

Biology research suggests that the closer you live to the equator, the more likely you are to have a girl. The tropics are known to have higher birth rates for girls than for boys.

Overall, a majority of babies born on Earth (51.5%) are boys. In fact, boys make up the majority of newborns in every country except for the Central African Republic. However, countries near the equator have a lower percentage of male babies than the global average (51.1-51.3%).

While still in the womb, baby boys are much more fragile than baby girls. Environmental influences can affect things like miscarriage rates and sperm quality. Research has shown that in times of extreme environmental stress, girls take an advantage over boys in birthrate.

The word 'Jazz' was thought to originate from Southern brothels, but recently it's been uncovered that a Baseball sportsjournalist used the word several times from 1912 to 1913.

A 15-pound cat chased a fully-grown black bear up a tree...twice!

On June 4th, an adult black bear sauntered into a New Jersey backyard, only to have met his match in an unlikely foe. That animal was none other than Jack, an orange-colored outdoor cat who, though territorial, no longer even had his front claws! Despite the bear’s immense size (up to forty times its own weight), Jack refused to back down. Oddly enough, his stubborn hissing actually scared the bear up a tree!

The cat remained at the base of the trunk for about 15 minutes and then scared the bear up ANOTHER tree when it tried to escape. Fortunately for this ‘fraidy bear, Jack was soon called into the house by his owner, which allowed the disproportionately fearful beast to flee back into the forest with everything but its pride still intact.

Adding the number 4 to the end of Facebook’s URL will automatically direct you to Mark Zuckerberg’s wall.

Just in case you’re not familiar with the term “URL” - type in this web address: www.facebook.com/4. We’re not sure why Zuckerberg chose the fourth ID number instead of number 1, but this is a quick and easy way to get to the original Facebook wall that is owned by its creator. Adding the numbers 5 or 6 to the end of the URL will take you to the respective profiles of Chris Hughes and Dustin Moskovitz, Facebook co-founders and Mark’s former college roommates. Tacking a 7 onto the web address leads to the profile of Arie Hasit, another good friend of Zuckerberg from his days at Harvard.
