As the years go by, we tend to think that we know our body almost perfectly. But it is a very complicated mechanism that sometimes surprises even doctors and scientists.
#1 Why do paper cuts hurt so much?
We have a lot of pain receptors in the tips of our fingers. Paper cuts are not deep so there's no blood to protect the damaged nerve endings and they are exposed to the irritants.
#2 What does a Bombay blood group mean?
This blood type was discovered in Bombay and is very rare. It is also called "Hh blood type" because it misses antigen H and has antibody h instead. People who have it can donate blood to other people with any ABO grouping but if they need blood transfusion themselves, they can receive it only from Bombay blood group people.
#3 What is proprioception?
It is an unconscious sense of movements and position of the body independent of vision. Without this sense you couldn't sit down or scratch your nose: you simply wouldn't be able to find it! A lot of nerves and muscles are involved to perform a movement or, for example, to lift a glass of water without throwing it into the face.
#4 Our brain is more active at night
You might think that all our actions and thoughts take a lot of powers and attention. It turns out the opposite is true. We need more brain power during our sleep.
#5 Women blink twice as many times as men do
#6 Everyone has a unique smell, except for identical twins
It is known that newborns are able to recognize the smell of their mothers. And grown-ups can identify the smell of their close people. It is formed by genetics, environment and our diet.
#7 Nose and ears never stop growing
Unlike eyes that remain unchanged from our birth, nose and ears continue to grow throughout the life.

Well, if our noses and our ears keep growing throughout our lives, it must be at an incredibly slow rate. I find this one hard to believe because I can't imagine how that works. My nose and ears appear to have been the same size for the past 45 years at least.

Diane Thompson,
Like it or not, it's true. It happens at a snail's pace, but it happens nonetheless.
Like children growing up, you don't notice day to day differences, but for someone who's been absent for a year, the growth is noticeable. It is the same for your nose and ears. It occurs more slowly, so it is even more difficult to see.

true ,you will notice as you get older, especially ,notice ears and noses of old men .

I believe eyes don't grow bigger , quite the opposite. When I was young I received many compliments on my big eyes, now in my 80's they appear much smaller and I notice it on other people too.

Interesting, specially - at least to me - item no.4.

Andoy Angeles, anecdotal evidence has no value unless there is verifiable statistical data to back it up.

Diane Thompson,
it is because noses and ears are mostly cartilage, not bone or fat or muscle. Bones stop growing after puberty and muscle and fat cells also stop dividing but cartilage continues to grow until we die. Some other good news is that gravity also makes earlobes elongate, making ears look larger.

It does and especially after age 65! The older you get, the more they grow, My Maternal Grandmother lived to be 97! Her ears were ao big! They were over 4 inches long and her mose too! He face and hair and head, were shrinking.

I have noticed noses on older, (that includes myself), people seem to fill out and if you look at a picture of a young man and another picture of the man much later in life, his head appears larger. I don't know if the head has actually grown or if it just filled out from fat deposits that accumulate as we age but there is definitely a change
