01. Did you know that Sharks have good eyesight? Yes, of course, sharks can see well in dark areas. They have fantastic night vision and can see colours. The back of sharks’ eyeballs have a reflective layer of tissue called a tapetum. This helps sharks see extremely well with little light. Another interesting fact about sharks is that they don’t have bones and that their cartilaginous skeletons are much lighter than normal bones. You may have seen their gills with which they filter oxygen from the water. In addition , their skin is like sandpaper because the skin has been made up of tiny teeth.

02. The average adult’s vocabulary consists of about 30,000 words.

03. Are you a lover ? If so, you are lucky because love can improve your heart health by reducing the risk of heart attacks. Amazingly, blister wounds inflicted on married couples heal faster.

04. Deep kissing increases the flow of saliva which contains substances which can fight against bacteria , viruses and fungi.

05. Ants are as old as dinosaurs. What do you know about ants ? You may have seen lines of ants at your home, but undoubtedly never have heard that ants do not have lungs and ears. If so, how do they breathe ? They breathe in oxygen through spiracles which are a series of holes located on the sides of their bodies. The spiracles are connected through a network of tubes which distribute the oxygen to almost every cell in their body. Not only that , ants can carry between 10 and 50 times their own body weight thanks to their tiny size.
