Why are Sharks so awesome ?

There are over 400 species of Sharks in our waters. And most of them are known to be fearless predators with huge teeth, Equipped with a great set of survival skills, They are one of nature's ruthless killing machines.

But how do they achieve this?

1. Flesh-eating sharks have about 3000 long or small sharp teeth that are arranged in 5 rows in the fleshy part of the jaw. Sharks can regrow its teeth that are damaged and broken very quickly-All the 3000 teeth in a lifetime !

2.They have a highly developed sense of smell. It is said that a shark can smell  blood from a distance of 500 meters !

3. Sharks can detect the heartbeat of the prey! They have sensory organs that allow them to detect the electrical currents of the prey within a radius of 100 meters !

4.Sharks also use a technique called electroreception. They can use their acute electric sense to detect the Earth's magnetic field by detecting the weak electric currents induced by swimming or by the flow of ocean currents.

5.Sharks are fast swimmers, This is obtained due to their streamlined body, Fins, gills. The fastest shark is the Mako shark that swims a 70 mph! And 96 mph when hungry !

Food for thought - Sharks have 8 senses.

Sharks are really awesome creatures and each shark has its own unique abilities, And it is a must to explore them.

Hypermobility

• Ever seen someone popping their joints and seeing their body parts be unusually more flexible than it is supposed to be?  
• This is called Hypermobility. 
• Joints that are more flexible than normal or that move in excess of a normal range of motion are considered Hypermobile.
• 20% of the population in the world are Hypermobile. 
• Compared to boys, Girls are more Hypermobile. Hypermobility tends to run in families, but its exact cause is unknown.
• Genes that are involved in the production of collagen, a protein important for joint, tendon and ligament function, are believed to play a role.
• Being double jointed has often increased the risk of asthma, Cardiovascular problems and bowel irritability. 
• Soon after, Researchers concluded that Hypermobility was linked to mental conditions as well. 
• Hypermobile people would be more prone to anxiety and increased flight or flight response.

Why do we sneeze ?

If you just sneezed, There was probably something irritating the inside of your nose. 

• Sneezing is the way of your body to remove an irritation from the inside of your nose. 
• When your nose feels irritated, It sends a message to a sneeze center of the brain, Where the brain sends signals to all the muscles to work together to create a sneeze.
• The muscles involved in the process are the stomach muscles, chest muscles, diaphragm muscles ( a thin sheet present at the bottom of the lungs ), Vocal cord muscles, throat muscles, and the eyelid muscles. 
• Have you noticed that we always close our eyes when we sneeze !
• Sneezing can send particles flying out of your nose at a speed of 100 miles per hour !! 
• people sneeze about 3 times in a row. Its just because those stubborn particles are just not getting out. It may need 2 or 3 more attempts.
• Have you ever felt like sneezing and were about to do it, But it just suddenly stopped? did you feel irritated and annoyed that the sneeze didn't pass? 
• Just look at a bright light ( not the sun ) and it will get you to sneeze.
