We all accept that getting older is inevitable, and now leading clinicians have revealed the exact age when different body parts start to decline, most alarming being the brain and lungs.
(1) Brain :-
It starts aging at 20 years age.
As we get older, the number of nerve cells - or neurons - in the brain decrease.We start with around 100 billion, but in our 20s this number starts to decline. By 40, we could be losing up to 10,000 per day, affecting memory, co-ordination and brain function.
(2) Gut :-
It starts aging at 55 years age.
A healthy gut has a good balance between harmful and 'friendly' bacteria. But levels of friendly bacteria in the gut drop significantly after 55, particularly in the large intestine. As a result, we suffer from poor digestion and an increased risk of gut disease. Constipation is more likely as we age, as the flow of digestive juices from the stomach, liver, pancreas and small intestine slows down.
(3) Breasts :-
It starts aging at 35 years age.
BY their mid-30s, women's breasts start losing tissue and fat, reducing size and fullness.
Sagging starts properly at 40 and the areola (the area surrounding the nipple) can shrink considerably.
(4) Bladder :-
It starts aging at 65 years age.
Loss of bladder control is more likely when you hit 65.Women are more vulnerable to bladder problems as, after the menopause, declining estrogen levels make tissues in the urethra - the tube through which urine passes - thinner and weaker, reducing bladder support.Bladder capacity in an older adult generally is about half that of a younger person - about two cups in a 30-year-old and one cup in a 70-year-old.
(5) Lungs :-
It starts aging at 20 years age.
Lung capacity slowly starts to decrease from the age of 20. By the age of 40, some people are already experiencing breathlessness.This is partly because the muscles and the rib cage which control breathing stiffen up.
(6) Voice :-
It starts aging at 65 years age.
Our voices become quieter and hoarser with age. The soft tissues in the voice box (larynx) weaken, affecting the pitch, loudness and quality of the voice. A woman's voice may become huskier and lower in pitch,whereas a man's might become thinner and higher.
(7) Hair :-
It starts aging at 30 years age.
Male hair loss usually begins in the 30s. Hair is made in tiny pouches just under the skin's surface, known as follices.A hair normally grows from each follicle for about three years, is then shed, and a new hair grows.Most people will have some gray hair by the age of 35. When we are young, our hair is coloured by the pigments produced by cells in the hair follicle known as melanocytes.
(8) Fertility :-
It starts aging at 35 years age.
Female fertility begins to decline after 35, as the number and quality of eggs in the ovaries start to fall.The lining of the womb may become thinner, making it less likely for a fertilised egg to take, and also creating an environment hostile to sperm.
(9) Eyes :-
It starts aging at 40 years age.
Glasses are the norm for many over-40s as failing eyesight kicks in - usually long- sightedness, affecting our ability to see objects up close.
(10) Heart :-
It starts aging at 40 years age.
The heart pumps blood less effectively around the body as we get older.This is because blood vessels become less elastic, while arteries can harden or become blocked because of fatty deposits forming on the coronary arteries - caused by eating too much saturated fat. The blood supply to the heart is then reduced, resulting in painful angina. Men over 45 and women over 55 are at greater risk of a heart attack.
