10 Becharming facts about ageing
The Flying by Years
Doesn’t it feel like you had just celebrated your last birthday and here you are celebrating with another candle on your cake? Those wrinkles have started to set in and you wonder how fast the years fly by. With ageing comes many joys and surprises and while you experience another phase of your life (middle-age), you compare your feelings about it with that of your friends’ or wife’s, but there are some universal truths that apply to everyone.
Number of Bones Decrease
When we are born, we have 350 bones in our skeleton, but as we grow and age, the number decreases to 206. No, we don’t lose those 144 bones, but they fuse together as we become adults.
Amount of blood Increases
A baby has only 250 mls of blood that circulates through the body. That’s equal to one cupful. The amount of blood circulating in an adult’s body is about four litres. This blood is pumped to all the tissues by the heart in about one minute while beating 75 times.
As you age, you can save money on deodorants because your underarm-perspiration decreases. Instead sweat comes in the form of hot flashes. As we age, the eccrine glands, which are sweat glands of our body become less sensitive and the action in our underarms decreases.
Every hour, we lose an average of 600, 000 particles of skin which compiles to approximately 1.5 pounds each year. By the time a person reaches 70 years of age, he/she would have lost around 105 pounds of skin.
Teeth Become Less Sensitive
As you age, your teeth will become less sensitive to hot or cold. It is because the inner hard tissues called dentin forms between your teeth enamel and nerves. Dentin provides an extra insulation and diminishes the pain response.
Brain Cells Can’t Regenerate
The only cells in our body that cannot regenerate are brain and nerve cells. Once brain cells are damaged and they cannot be replaced. It is because of this fact that we are born with all our brain cells and the human head is one-quarter of our total length at birth, but only one-eighth of our total length by the time we reach adulthood.
Colds become Fewer
By the time you reach middle age, you have been exposed to so many cold-causing viruses that you develop immunity against them and thus, get sick less. According to the American Lung Association, while young children get cold six or eight times a year, adults get them between two and four times a year.
As we age, our breathing rate slows down and by 60 years of age, breathing becomes difficult. Snoring affects 60 percent of men and 40 percent of women by old age. Usually the snores have a noise level of 60 decibels, which is the same as normal speech. But sometimes they are as loud as 80 decibels which is equal to the sound of a pneumatic drill breaking up concrete. Noise levels over 85 decibels can damage the human ear.
Migraines Disappear in Women
Menopause can be nasty but it can bestow some advantages too, like it can chase away migraines in about 67 percent of the time for migraine sufferers. It happens because menopause causes your hormone levels to lay consistently low.
An adult eats approximately 500 kg of food every year and produces 1.7 litres of saliva each day to process this food. The digestive system runs 11.5 litres of digested food every day; liquids and digestive juices flow through it out of which only 100ml is lost in faeces. To ensure proper digestion of all this food enough strong acids are required, and thus a new stomach lining is produced every three to four days by the body.
