When does the brain stop growing?
We used to think that the brain was fully developed by very early teenagerhood and we now realise that the brain doesn't stop developing until mid-20s or even early 30s. There's a lot more information and evidence to suggest that actually brain development in various forms goes on throughout the life span.

How much water is inside the human body?
By one year of age, that amount drops to about 65%. In adult men, about 60% of their bodies are water. However, fat tissue does not have as much water as lean tissue. In adult women, fat makes up more of the body than men, so they have about 55% of their bodies made of water.

Do evergreen trees lose their leaves?
Deciduous trees shed their leaves usually as an adaptation to a cold or dry season. Most tropical rainforest plants are evergreens, replacing their leaves gradually throughout the year as the leaves age and fall, whereas species growing in seasonally arid climates may be either evergreen or deciduous.

How fast can a camel go?
However, camels can carry more weight and can move at average speeds of about 12 kilometer per hour for as much as 18 hours. A fast, unladen camel can attain speeds of over 60 kilometers per hour (while fast racehorses can peak at about 65 kilometers per hour). On sand, however, the camel will beat the horse in a race.

Do apples help clean your teeth?
The acid needs the help of the fiber-rich flesh of the apple. Start stocking your fridge with a variety of crunchy fruits and vegetables. Crunchy foods such as apples, celery, and carrots, act like mini toothbrushes when you chew them. Eating these types of foods can actually help scrub away stubborn stains over time.

Why is the left lung smaller than the right lung?
The left lung is slightly smaller than the right lung because 2/3 of the heart is located on the left side of the body. The left lung contains the cardiac notch, an indentation in the lung that surrounds the apex of the heart. Each lung consists of several distinct lobes.

What do you call the space between your nose and upper lip?
For humans and most primates, the philtrum survives only as a vestigial medial depression between the nose and upper lip. The human philtrum, bordered by ridges, also is known as the infranasal depression, but has no apparent function.

Why are the atomic masses listed on the periodic table not whole numbers?
The atomic mass reported on a periodic table is the weighted average of all the naturally occuring isotopes. Being an average it would be most unlikely to be a whole number. The mass of an individual atom in atomic mass units is the mass relative to carbon-12.

Where does the black rose grow?
Called the Turkish Halfeti Rose, they only grow in exceptionally small numbers in the village of Halfeti, Turkey. They won't flourish anywhere else in the entire world because it's the river Euphrates that provides the ideal soil and growing conditions for the rose.

How much does the temperature change with altitude?
Although the actual atmospheric lapse rate varies, under normal atmospheric conditions the average atmospheric lapse rate results in a temperature decrease of 6.4C°/km (3.5F°/1,000 ft) of altitude above ground level. The measurable lapse rate is affected by the moisture content of the air (humidity).

How much does a tongue of a blue whale weigh?
Blue whales are the largest animals ever known to have lived on Earth. These magnificent marine mammals rule the oceans at up to 100 feet (30 meters) long and upwards of 200 tons (181 metric tons). Their tongues alone can weigh as much as an elephant.

What percentage of the world's population has green eyes?
Green eye color is often confused with hazel eye color, yet is entirely separate and distinct. Green eye color is the rarest color found around the world, and it is estimated that only around 2% of the world's population has green colored eyes.

What were the wisdom teeth used for?
Anthropologists believe wisdom teeth, or the third set of molars, were the evolutionary answer to our ancestor's early diet of coarse, rough food – like leaves, roots, nuts and meats – which required more chewing power and resulted in excessive wear of the teeth.

Is alcohol a vasodilator or vasoconstrictor?
At intoxicating levels, alcohol is a vasodilator (it causes blood vessels to relax and widen), but at even higher levels, it becomes a vasoconstrictor, shrinking the vessels and increasing blood pressure, exacerbating such conditions as migraine headaches and frostbite.
