From massive beasts to tiny creepy-crawlies，the following creatures have a reputation for being killers-but they really aren't all that deadly to humans as you think.
For decades.Hollywood filmmakers have described sharks as toothy killing machines with a taste for human flesh.But shark attacks are probably much rarer than you think.Some species of sharks.like the whale shark，don't pose a threat to humans at all.despite looking prety menacing.One average，sharks are responsible for sis human deaths a year.
Lions and tigers and bears.oh my God！"While the cowardly Lion is the gentle giant who befriends Dorothy's gang in the film The Wicard of O=，bears are actually the least deadly of the three animals from this famous scene.Estimates of human deaths by lions and tigers can range from 50-100.highest in countries such as Tanzania and India.Combined，brown and black bears only kill an average of one to three humans a year in their native United States and Canada.
Don't get us wrong-black widow spiders are deadly. But many types of spiders-even some of the biggest and scariest-looking ones-don't often bite and certainly can't kill you. Spider bites cause an average of seven human deaths per yearin the United States. That's fewer than the number caused by significantly less feared creatures like ants, bees, and, believe it or not, freshwater snails.
These big cats-which you might also call cougars or pumas-are native to North America and are the subject of cautionary tales for many a hiker. Despite that.there are only 25 human deaths by mountain lions on record, period, since 1890.That's an average of one every five years. While they have been known to kill pets, deer, and livestock, mountain lions probably shouldn't be high on humans' list of animals to be afraid of.

Back at Dal. komm Coffee,a robot can make about 300 cups a day at the cost of $2 to $3. While some customers like the robot coffee maker, others do not.Personally I prefer the human coffee maker,"said Lee Sang Jim.

The boys were up to their necks in iey water and quickly losing feeling in their limbs. Any chance of their freeing themselves was slipping away. Cruz was sure he was going to dic.

Secing the boys, he grabbed a nearby buoy. kicked off his shoes, and ran into the slushy water, chopping his way through the ice with his free fist. It was kind of a' Hulk smash.""Lavin told NBC5 Chicago.
Lavin made his way to Cruz and Anthony and hauled them back to land. They were taken to the hospital. where doctors discovered that their five-minute stay in the water had lowered their body temperature nearly ten degrees.
