A human being produces about half a litre of saliva per day. Some even reach two litres daily. This amount accumulated over a lifetime would be enough to fill two Olympic swimming pools.
A human bone is stronger than a steel bar of the same size and thickness. Still, it is possible to fracture it, as many of us have experienced. Also the human body has a total of 206 bones. Over a quarter of them are at the bottom: in the feet. Each foot has 26 bones: 7 tarsals, 5 metatarsals and 14 phalanges (three in each toe, except for the largest which has two).

We can try it hundreds of times, but we’ll never be able to sneeze with our eyes open. Have you tried?
The brain’s storage capacity, if it were compared to a computer, would be 10 to 100 terabytes. Some scientists even assume this figure to be 2.5 petabytes or 2.5 million gigabytes. Hypertext Magazine calculated that this would be the equivalent of storing 3 million hours of videos.
A nerve impulse, once sent from the brain, travels through the body at a speed of 274km/h.
The accumulated length of the body’s blood vessels is almost 100,000 kilometers.
The sensation of thirst appears when the body loses the equivalent of 1% of its body weight. A loss of 5% represents a severe degree of dehydration and may cause fainting. If the decrease is greater than 10%, it could cause death.
A 4-year-old can ask up to 450 questions a day.

Scientists estimate that the human eye is able to distinguish up to 100 colour variations that combine in up to 1 million colour tones.
The muscles of the eyes that allow us to focus on images move about 100,000 times a day. This effort would be the equivalent of walking 80km a day.
From the age of 60, people lose many of their taste receptors. However, the sensation of what pleases the palate does not disappear.
Our eyes are the same size as when we were born, but our noses and ears never stop growing. This behavior happens due to their cartilaginous formation that deforms the body parts with the force of gravity.

A person has about 250 lashes in each eye. The lifespan of these lashes is 4 months, so they grow much faster than the hair on the head.

Fingers help us use our strength in everyday life, but they don’t have muscles. They’re composed of bones and tendons only.
