人体器官衰老时间表（Human organ aging schedule）Human organ aging schedule (Photos): classification of health care.According to the British Daily Mail reported on your own body really understand? Human organs and tissues with aging pattern, the famous French physician Angela Epstein said, at the age of 35 male sperm quality began to deteriorate, when a 45 year old male, 1/3 are pregnant abortion. At present, in a number of famous British physician's help, they jointly assess different body tissues and organs of the aging schedule.1, 20 years old start aging brain:With the increase of age, the number of nerve cells in the brain to reduce. Before the body of nerve cells in the brain of 100 billion, at the age of 20 began to gradually reduce. By the age of 40, the daily loss of nerve cells in the brain 10 thousand, corresponding with memory loss and brain dysfunction.In fact, the nerve cells in the brain is very important, the British Imperial College London health care center consultant neurologist Wojie Taco Rakoviciz said that with the increase of age, the gap between brain cells become worse have greater impact on health. The small gap between the peripheral nerve cells in the brain called synapses, synaptic function can ensure that from one nerve cell to another transmission of information, with fewer synapses of aging.2, intestinal: 55 years old start agingA healthy gut can establish a good relationship between the balance of bacteria harmful and harmless, the Tom MacDonald professor of immunology medical school in London, but when people over the age of 55, intestinal digestive system in harmless cell index decreased gradually. The end result is that we will suffer from digestive ability is abate, increase intestinal diseases. Which is a symptom of constipation with body in the elderly often show.3, breast: 35 years old start agingWhen women enter the age of more than 30, it began to lose fat and breast tissue, breast size and fullness began to decrease. When women enter the age of 40, the breast sagging, areola began corresponding contraction. Although with the increase of age, will increase the probability of occurrence of breast cancer, often need specific massage stimulation can effectively prolong breast health.4, bladder: 65 years old start agingWhen people enter the age of 65, is likely to gradually weaken the control of the bladder, bladder function decreased with the aging of the human body is very obvious, but not completely. Women are more prone to bladder problems, when they experienced 65 years after menopause, estrogen decrease in urethral tissues thinner and weaker, to reduce bladder support. The elderly bladder capacity compared with middle-aged, middle-aged people only half. For 65 years old people, they are more prone to frequent travel.5, lung: 20 years old start aging6, the reproductive capacity: 35 years old start agingThe male sperm has a special function on ovarian maintenance without the normal 2-4 times a month of life of the female reproductive capacity began to decline from the age of 35, the quality of oocytes in the ovaries began to fall so women often than men are more likely to grow old. But the uterine wall becomes thin, so that to reduce the probability of fertilization, while the formation of a hostile environment for sperm.The male reproductive capacity decreased with increasing age, when they enter the age of 40, his spouse abortion is a high probability, the reason is the decline in sperm quality.7, eyes: 40 years old start agingWhen people enter the 40 year old, very common to many people will choose to use glasses, they appear presbyopia, will affect our ability to see objects close. The British University of Southampton ophthalmology professor Andrew Loty said that with the increase of age, the deterioration of eye visual focusing ability, the reason is that the eye muscles become weak.8, liver: 70 years old start agingThis is the only challenge the aging process of human body organs and tissues, British Leicester liver consultant David Lloyd explained that the liver cells have very strong functionof a new life.He pointed out that after the removal of a liver during surgery,Within three months will be long with a same size of liver. If donors do not suffer from infection or drinking, smoking, can be a 70 year old man with liver transplantation into the body of a 20 year old young man.9, kidney: 50 years old start agingWhen people enter old age, the filtration unit of the kidney in the bloodstream is responsible for removing the waste (kidney) to reduce the number of start. One effect is weaken the ability of nocturnal urine production, so they frequent phenomenon in out. The ability of 75 year old renal blood filtering is equivalent to only half of the 35 year old man.40 years old start aging heart10, heart: 40 years old start agingWith the increase of age people, the heart pump output was significantly reduced. The reason is due to the formation of vascular elasticity, accumulation of fat in the coronary arteries, the arteries become stiff and blocking. This is the excessive intake of saturated fat causes. Then the heart's blood supply.After entering the age of 45 male and female 55, will increase the probability of heart attack. Lloyd Famasi is the lateststudy found that the average British people into "heart disease age" 5 years in advance, this may be due to obesity and lack of exercise caused by.11, prostate: 50 years old start agingProfessor Roger Kirby director of the London prostate Center said that with the increase of age, the prostate often become hypertrophy, resulting in frequent phenomenon. This is 50 years after more than half of the men appear prostate hyperplasia, but rarely in the disease appear before the age of 40.Prostate hyperplasia is because prostate absorbs a lot of testosterone, thereby enhancing the growth of prostatic cells. The normal prostate size only general prostatic hyperplasia after walnut, but will increase to the size of oranges.12, bone: 35 years old start agingThe city of Liverpool, in the ante Robert Motts rheumatology medical school professor explained, in our life, the old bone is called a osteoclastic bone destruction, and called by osteoblasts bone manufacturing cells to generate new bone, a process called skeletal cyclical manufacturing.The children's bone growth is very fast, children two years of bone turnover, adults are completely in 10 years. Until we are more than 20 years old, bone density continues to increase, but at the age of 35, as a part of human aging, bone density decreased.This makes the probability of postmenopausal osteoporosis in elderly women with increased size and density of bone shrinkage decreases, resulting in reduced height so that normal life is very important for women to postpone menopause coming greatly. The back bone begins to atrophy, or between vertebral bone fragments. When people are 80 years old, the height will decrease 2 inches.13, teeth: 40 years old start agingWith the increase of age, the body will produce less saliva, the saliva can wash away bacteria, so the teeth and gums are more vulnerable to decay. As mankind has entered the 40 year old, the gum gradually began to decay.14, muscle: 30 years old start agingMuscle tissue is often built and decomposed, this process has a very good balance in young adults. However, when people enter the age of 30, greater than the formation and decomposition of muscle tissue. Once people enter the age of 40, people began to lose every muscle 0.5-2%. Have regular physical exercise can help to avoid this phenomenon.15, listening: more than 50 years old start agingBased on the analysis of the Royal British Deaf Association statistics, due to age into old age, more than half of the 60 people will lose their hearing. This is called senile deafness, is due to the loss of "hair cells" formation. Hair cells are a tiny sensory cells in the inner ear, it can obtain the soundof fibrillation, and the fibrillation is sent to the brain tissue.16, more than 20 years old start aging skin:Human skin natural aging is starting from the age of more than 20, according to the Brad Ford Medical Center dermatologist Andrew Wright said, when we grow old,As a scaffold of skin collagen formation ability decreased, elastic material can cause the skin to restore in situ protein also have less activity, more likely to break down.Dead skin cells will not fall off very quickly, which makes the new skin cells slightly reduced.17, taste and smell: 60 years old start agingOur life in the long tongue 10 thousand taste buds, but in the 60 years after the decrease in the number of taste buds to half. As we enter the 60 year old, the ability to taste and smell gradually weakened, partly due to the aging factor. Olfactometer may be because of a problem in the nose polyp, may also be due to the formation of the accumulation of years of smoking.18, voice: 65 years old start agingWith the increase of age, our voice will become hoarse sound and, 65, the soft tissue in the throat will gradually become weak, thus affecting the pitch, loudness and quality of thethroat sound; the female voice may become hoarse tones and lower than men, their voice will become thin and high pitched tone.19, hair: 30 years old start agingMale hair phenomenon usually appears at the age of 30, after the hair is from the skin under the surface of small bag shaped hair follicle formation. A hair is usually from hair follicles grow, after 3 years off, and then the new hair grow. However, effects of a 30 year old male testosterone levels by early cycle changes, lead to hair follicles contraction hair phenomenon.In this way, each new hair is more fine than before, eventually all the hair follicles increasingly shrink, fine hair does not grow from the hair stubble. Many people after 35 years there will be a lot of gray hair, when we are young, our hair is a hair follicle melanocytes pigment formation control. As we age, activity of melanocytes decreased, less melanin, the hair color fades, gray hair gradually appeared.-------------------------------------------Male physiological digital funThe 7200 man average ejaculation frequency2000 times the average man masturbation ejaculation frequencyThe average weight of 53 liters of man ejaculationThe average speed of 45 km men ejaculation: speed of 45 km, whilethe average bus speed is 40.2 kilometers per hour.11 times the average daily number of men with erectile The 9 man day night average erectile number2.5 months of sperm life: 2.5 months (from generation to ejaculation)。
