Astronauts have to sleep near fans or they could die in their sleep!

In a complete opposite of the South Korean fan death myth, it turns out astronauts actually NEED to sleep next to a ventilator fan while they're in weightless orbit. Why? If they don't, they might suffocate in their sleep.

The reason is because warm air doesn't naturally rise when there's no gravity. If you don't have a way of circulating air, then the carbon dioxide you expel when you breathe can form a bubble around your nose. Eventually, the air available to you wouldn’t have enough oxygen and you would die.

Lawns became popular in the 17th century as a symbol of wealth!

A well-kept vibrant green lawn is the pride of many people in suburbia. Lawns are a status symbol, now, and ever since they first became popularized. The reasons, however, have changed dramatically.

In the early Jacobean epoch of 17th century England, the closely cut 'English' lawn was born. By the end of this period, having an English lawn was seen as a symbol of status of the aristocracy and gentry. It showed that the owner of the field could afford to keep land that was not being used for a building or for producing food.

Today, they are still seen as a status symbol. However, since the 2008 recession, many communities have dug up their lawns and planted fruit and vegetable gardens. The result could be that lawns will be viewed as environmentally and economically unviable at some point in the near future.

Lobsters are potentially immortal!

Scientists have recently discovered that lobsters might have the potentially live forever. That is, unless it's in front of you while you're wearing a bib at Red Lobster. Scientists have described lobsters as 'eating, molting, and growing machines.'

Lobsters don't stop growing. The biggest one's they've observed weigh more than 40 pounds. However, they think there could be much bigger lobster in the ocean because it appears lobsters just wear out very slowly.

More specifically, lobsters show no signs of aging. They don't lose appetite, sex drive, energy or even experience changes in metabolism as they grow older. This means that barring predators or disease, they really could potentially live forever.

Guinness gave the world record for 'most lawsuits filed' to a man. He sued them for it!

Jonathan Lee Riches is infamous for the number of lawsuits he's filed in various US district courts. One of the most ironic is that the Guinness Book of World Records named him the 'most litigious individual in the history of mankind'… and he sued them for it!

All in all, he's filed over 2600 federal lawsuits. Among the named defendants are George W. Bush, Perez Hilton, Britney Spears, Michael Vick, the INS, and even Somali pirates. He also filed a restraining order against the makers of Grand Theft Auto because he said inmates who play the game might be influenced to knock him out.

He has also filed a lawsuit against Kanye West and Kim Kardashian as being terrorist, and even named the Eiffel Tower, all the survivors of the Holocaust and even Plato as a defendant in some of his lawsuits.

At one point Riches was incarcerated at Federal Medical Center in Kentucky for wire fraud. He was released in April 2012, and arrested for violating his probation in December when he allegedly drove to Connecticut and impersonated the uncle of the shooter in the Sandy Hook incident.

There's a hiking trail that connects Delaware and California!

Did you know that you can literally hike from the Pacific to the Atlantic ocean on a single hiking trail? It's called the American Discovery Trail and it spans over 6,800 miles. It's the only non-motorized coast-to-coast trail.

The trail passes through 14 national parks and 16 national forests. It also passes through 15 states, 10 National Historic Trails, and 23 Natural Recreation Trails. Surprisingly, the first time the trail was hiked coast to coast was in 2005.

Marcia and Ken Powers, couple from Pleasanton California started out from Cate Henlopen State Park in Delaware and finished in Point Reyes, California. They walked 5,058 miles by foot. It took them from February 27, 2005 to October 15, 2005 to complete their trek.
