The growth of human hair\n\nEach human head carries roughly 100,000 hair follicles. \nEach follicle can grow many hairs over a lifetime: on average, each grows a new hair around twenty times. \nNot all these follicles are actively growing hairs at any one time. From the moment when it is first formed, each follicle undergoes repeated cycles of active growth and rest. The length of the cycle varies with the individual, and also with the part of the body on which the hair is growing. \nThe hairs on an adult scalp do not grow in unison, as they do in an unborn baby. They are 'out of cycle' with each other. If this were not so, everyone would go temporarily bald from time to time. \nThe growing and shedding of hair as a whole seems to happen at random, but for each hair follicle the process is precisely controlled. No one knows for certain, however, exactly how the body controls these cycles. \nPlucking a hair from a follicle brings forward the next period of hair growth in that follicle\nOver the years, the number of follicles capable of growing hair declines naturally. The decline is especially noticeable on the top of the head. Some follicles increasingly produce only fine, short non-pigmented hairs that look more like vellus hairs than terminal hairs. In older women, this leads to a general thinning of hair. In men it tends to lead to common baldness. If you look at a bald scalp you will see these fine, poorly pigmented hairs.

Yeah I did... Makes sense too, because you're head is like 80% of its adult size by the time we are two years old, so if our ears stayed the same size from when we were children, we'd probably look a little weird if the ears and nose didn't grow with our height and what not... Hehehe... Interesting tidbit of info though...

Well, hair is part of the skin, as you get old, your skin shows, rigtht, no wonder why the hair does too.

if you are asking why older people cant hear higher sounds this is why...Sound is collected by the pinna (the visible part of the ear) ...yada yada yada... the vibration is eventually transferred to the snail-shaped cochlea in the inner ear; the cochlea is lined with sensitive hairs which trigger the generation of nerve signals that are  sent to the brain. People can usually hear sounds in the frequencies between 20 and 20,000 Hertz at birth. The higher frequencies are picked up by the smaller hairs, which are more brittle. As we age the more brittle ones break off and thus we lose our abilty to hear high frequencies.

Ringing of the ear is called Tinnitus.\nInside your inner ear, thousands of auditory cells maintain an electrical charge. Microscopic hairs form a fringe on the surface of each auditory cell. When they're healthy, these hairs move in relation to the pressure of sound waves. The movement triggers the cell to discharge electricity through the auditory nerve. Your brain interprets these signals as sound.\n\nIf the delicate hairs inside your inner ear are bent or broken, they move randomly in a constant state of irritation. Unable to hold their charge, the auditory cells "leak" random electrical impulses to your brain as noise.\n\nDamage to auditory cells in your inner ear most commonly results from:\n\nAge-related hearing loss (presbycusis). This process usually begins around age 60. \nNoise-related damage to your inner ear. This erosion of your hearing ability may result from excessive exposure to loud noise over a long period of time. Tractors, chain saws and weapons are common sources of noise-related hearing loss. Portable music devices, such as MP3 players or iPods, may become a common source of noise-related hearing loss in the future if people play these devices loudly for long periods. \nOther causes of tinnitus may include:\n\nLong-term use of certain medications. Aspirin used in large doses and certain types of antibiotics can affect inner ear cells. Often the unwanted noise disappears when you stop using these drugs. \nChanges in ear bones. Stiffening of the bones in your middle ear (otosclerosis) may affect your hearing. \nInjury. Trauma to your head or neck can damage your inner ear. \nCertain disorders of your blood vessels can cause a type of tinnitus called pulsatile tinnitus. These may include:\n\nAtherosclerosis. With age and buildup of cholesterol and other fatty deposits, major blood vessels close to your middle and inner ear lose some of their elasticity — the ability to flex or expand slightly with each heartbeat. That causes blood flow to become more forceful and sometimes more turbulent, making it easier for your ear to detect the beats. \nHigh blood pressure. Hypertension and factors that increase blood pressure, such as stress, alcohol and caffeine, can make the sound more noticeable. Repositioning your head usually causes the sound to disappear. \nTurbulent blood flow. Narrowing or kinking in a carotid artery or jugular vein can cause turbulent blood flow and head noise. \nMalformation of capillaries. A condition called A-V malformation, which occurs in the connections between arteries and veins, can result in head noise. \nHead and neck tumors. Tinnitus may be a symptom of a tumor in your head or neck.  \n\nSo as not to cause panic.  Maybe it's just a simple case of water trapped in your ear. or an infection called otitis media.  It would be prudent for you to go see an EENT for proper diagnosis. and treatment.  All you need might only be an ear irrigation.\n\nTinnitus is usually caused by a head injury, an infection, such as colds or sinus infection or sinusitis, a disease or exposure to loud sounds such as gunshots and explosions.\n\nIt can be a sign of hearing loss, or it can result from head injuries, or diseases that range from the common cold to diabetes. People who work with noisy equipment, such as power tools, can also get it. Or tinnitus may be initiated by a single loud noise, such as a gunshot or an explosion. It can also be a symptom of almost any ear disorder, including the following:\n\n Ear infections \n Blocked ear canal \n Blocked eustachian tube \n Otosolerosis \n Tumors of the middle ear \n Meniere's disease \n Damage to the ear caused by drugs (such as aspirin and some antibiotics) \n Hearing loss \n Blast injury from a blast or explosion \n\nTinnitus may also occur with other disorders such as anemia, heart and blood vessel disorders including hypertension and arteriosclerosis, and low thyroid hormone levels in the blood (hypothyroidism).\n\nA wide variety

My guess, and it's only a guess is that it traps our own unique scent, which then attracts "mates."  Obviously, we only grow hair under our arms at puberty, and what occurs at puberty is that our sex organs develop, so that's the rationale behind my answer.  However, I do not know the biological reason why humans have relatively long hair in their armpits!

It's because of the scab. It is just like dry skin. The old skin dries up and new grows underneath.

Your hair loss could be a hormone problem.

Of course they get gray hair! I don't know about baldness, but most have, thick coarse hair, which to me would be less likely to have baldness. My great grandfather was (part) Cherokee, lived to be 93, and did have some balding.

What you may have noticed is the when people have been married a long time they tend to be older. (1+1=2) When women get older the tend to whear thier hair shorter. So, when you see a couple that's been married for 50 years chances are she'll have short hair.

They do sound young, don't they?\n\nLet's just say I'm middle-aged.

Cartilage never stops growing, which is why older people tend to have larger ears and noses.
