There are many types of lethal venom in the animal kingdom, but perhaps no stranger carrier than the platypus. The platypus is one of few venomous mammals. Male platypus carry venom cocktail in their ankle spurs. This venom incapacitates victims with excruciating pain. Stranger still, the platypus is the only mammal that uses electroreception. That means that the platypus uses its bill to sense the electricity produced by the muscular movements of its prey. Electroreception is a sixth sense different from seeing, hearing, smelling, tasting, or feeling. Perhaps most odd, the platypus is the only mammal that lays eggs rather than giving birth to live young. What an odd creature indeed.

The term "amnesia" refers to complete or partial memory loss. Almost all of us will experience some form of amnesia in our lives, even if it's just a simple case of verbal amnesia, like forgetting someone's name. Fortunately, there are things that you can do to prevent amnesia. Here is a list of foods that you can eat to improve your memory: almonds, walnuts, bananas, honey, apples, and black pepper. Though these foods may not reverse post-traumatic amnesia, they should improve your memory in daily life if you eat them regularly enough.

Today's economy is tough, but there are a lot of ways that you can cut back. Instead of paying big bucks to some fancy mechanic, you can change your own oil. First, put on some clothes and safety gear. Once you are properly dressed, crawl under your car and remove the oil plug. Drain the oil into an oil pan. Wait a few minutes to make sure that the old oil has drained completely, and then replace the oil plug. Remove the oil filter. Replace it with a new one and pour four or five fresh quarts of oil into your car's engine. Wasn't that easy?

Ansel Bourne was a preacher, carpenter, and most likely an inspiration for the name "Bourne" in the movie and novel series "The Bourne Identity." Up until 1857, Bourne had been a carpenter, until he was called into religion. After 1858, he worked as an evangelical preacher, until 1867. He set up shop in Norristown, Pennsylvania, as a candy maker using the name A.J. Brown. Three months later, he woke up not knowing where he was, with no memory of the previous months. The case of Mr. Bourne has fascinated psychologists, and some film makers, for years.
