Article: A lot of people these days believe Valentine's Day is a made-up holiday designed to promote the sale of greeting cards and gifts. And while there may be some Arguments for that, there is a mysterious story as to why February 14th has become known today as "Valentine's Day." Our story dates back centuries ago, to the Roman Empire, and the martyrdom of two or three Christians named Valentine. At least one of those Valentines is thought to have been killed on February 14th. Legend has it that this particular Valentine wais killed by a Roman emperor because he secretly presided over the marriages of young men and women, against the wishes of the Emperor, who wanted only single men to fight in his army. However, there is no historical evidence to back this up. But what is widely known is that the love-element to Valentine's Day can be first traced to the poetry of Geoffrey Chaucer. Chaucer wrote a poem in 1382 to mark the anniversary of his King's engagement, and scribed a line -- "For this was Saint Valentine's Day, when every bird cometh there to choose his male." From this point, on Valentine's Day became intertwined with love. But for the pessimists out there who see Valentine's Day as a commercial idea, there is some historical evidence to back this up as well! The true popularization of Valentine's Day can be traced to late 18th century England, when a British publishing company first started selling paper Valentine's Day cards with tender words on them. They became so popular that by the middle of the 19th century, some 1.3 billion British pounds a year were being spent on Valentine's Day gifts.

Article: Pets are popular. They're good listeners, they encourage us to exercise, and they're always on our side when we argue with others. They can bring people comfort and pleasure. But it is important to keep in mind that pets can carry diseases that can make you sick. Washing your hands often -- especially after you touch, feed, or clean up a pet -- is the best way to keep yourself healthy and prevent the spread of disease. Be sure to clean your fingernails carefully every time you wash. You also can protect your health by wearing gloves while cleaning animal cages or cat litter boxes. Avoid washing your pet in the bathtub , but if you do, always disinfect the tub immediately afterward. Be sure to bring your pet to the hospital for examinations every two weeks or month and whenever your pet is sick or injured. You can do a few other things to keep yourself and your pet healthy. Only give your pet food that has been planned ahead for them. It's not a good idea to share your food with your pet. Human food (like chocolate) can make animals sick. Never feed your pet raw meat because it can carry germs that cause serious illness. And funny as it can be to see your dog or cat drinking from the toilet, don't let pets do this. It's bad for your pet's health! Give them clean, fresh water to drink at all times. Never give milk to cats. The only milk an animal should drink is from its mother. Cow's milk is not for pets, especially for cats, as _ makes them sick. Finally, some animals aren't pets. Don't take in a wild or abandoned animal as a pet because it may have diseases that could make you or your family sick. Instead, turn to an animal rescue group that is trained in helping sick or abandoned animals.
