Aging: What to expect as you get older

Looked in the mirror lately only to find a few more wrinkles and gray hairs? Those are just a few of the changes you're likely to notice as you get older. But what exactly is going on with your body? Here's what you can expect as you age.

Natural changes with age

Regardless of how long you live, time takes a toll on the organs and systems in your body. How and when this occurs is unique to you. Some typical changes to expect as you age include:

Cardiovascular system
Over time, your heart muscle becomes a less efficient pump, working harder to pump the same amount of blood through your body. Also, your blood vessels become less elastic. Hardened fatty deposits may form on the walls of your arteries (atherosclerosis), narrowing the passageway through the vessels. The natural loss of elasticity, in combination with atherosclerosis, makes your arteries stiffer, causing your heart to work even harder to pump blood through them. This can lead to high blood pressure (hypertension).

Bones, muscles and joints
Your bones reach their maximum mass between ages 25 and 35. As you age, your bones shrink in size and density. One consequence is that you might become shorter. Gradual loss of density weakens your bones and makes them more susceptible to fracture. Muscles, tendons and joints generally lose some strength and flexibility as you age.

Digestive system
Swallowing and the motions that automatically move digested food through your intestines slow down as you get older. The amount of surface area within your intestines diminishes slightly. The flow of secretions from your stomach, liver, pancreas and small intestine may decrease. These changes generally don't disrupt your digestive process, so you may never notice them. But you might notice more constipation.

Kidneys, bladder and urinary tract
With age, your kidneys become less efficient in removing waste from your bloodstream. Chronic conditions, such as diabetes or high blood pressure, and some medications can damage your kidneys further.

About 30 percent of people age 65 and older experience a loss of bladder control (urinary incontinence). Incontinence can be caused by a number of health problems, such as obesity, frequent constipation and chronic cough.

Women are more likely than men to have incontinence. Women who've been through menopause might experience stress incontinence as the muscles around the opening of the bladder (the sphincter muscles) lose strength and bladder reflexes change. As estrogen levels decline, the tissue lining the tube through which urine passes (urethra) becomes thinner. Pelvic muscles become weaker, reducing bladder support.

In older men, incontinence is sometimes caused by an enlarged prostate, which can block the urethra. This makes it difficult to empty your bladder and can cause small amounts of urine to leak.

Brain and nervous system
The number of cells (neurons) in your brain decreases with age, and your memory becomes less efficient. However, in some areas of your brain, the number of connections between the cells increases, perhaps helping to compensate for the aging neurons and maintain brain function. Your reflexes tend to become slower. You also tend to become less coordinated.

Eyes
With age, your eyes are less able to produce tears, your retinas thin, and your lenses gradually turn yellow and become less clear. In your 40s, focusing on objects that are close up may become more difficult. Later, the colored portions of your eyes (irises) stiffen, making your pupils less responsive. This can make it more difficult to adapt to different levels of light. Other changes to your lenses can make you sensitive to glare, which presents a problem when driving at night. Cataracts, glaucoma and macular degeneration are the most common problems of aging eyes.

Ears
Hearing loss is one of the most common conditions affecting adults who are middle-aged and older. One in three people older than 60 and half of all people older than 85 have significant hearing loss. Over the years, sounds and noise can damage the hair cells of your inner ears.

Also, the walls of your auditory canals thin, and your eardrums thicken. You may have difficulty hearing high frequencies. Some people find it difficult to follow a conversation in a crowded room. Changes in the inner ear or in the nerves attached to it, earwax buildup and various diseases can all affect your hearing.

Teeth
How your teeth and gums respond to age depends on how well you've cared for them over the years. But even if you're meticulous about brushing and flossing, you may notice that your mouth feels drier and your gums have pulled back (receded). Your teeth may darken slightly and become more brittle and easier to break.

Most adults can keep their natural teeth all of their lives. But with less saliva to wash away bacteria, your teeth and gums become slightly more vulnerable to decay and infection. If you've lost most or all of your natural teeth, you might use dentures or dental implants as a replacement.

Some older adults experience dry mouth (xerostomia), which can lead to tooth decay and infection. Dry mouth can also make speaking, swallowing and tasting difficult. Oral cancer is more common among older adults. Your dentist checks for oral cancer when you go for regular cleanings and checkups.

Skin, nails and hair
With age, your skin thins and becomes less elastic and more fragile. You'll likely notice that you bruise more easily. Decreased production of natural oils may make your skin drier and more wrinkled. Age spots can occur, and skin tags are more common. Your nails grow at about half the pace they once did. Your hair may gray and thin. In addition, you likely perspire less — making it harder to stay cool in high temperatures and putting you at increased risk of heat exhaustion and heat stroke.

How fast your skin ages depends on many factors. The most significant factor is sun exposure over the years. The more sun your skin has been exposed to, the more damage you may attain. Smoking adds to skin damage, such as wrinkles. Skin cancer also is a concern as you age. You have a 40 percent to 50 percent chance of getting skin cancer at least once by the time you reach 65.

Sleep
Sleep needs change little throughout adulthood. If you need six hours of sleep nightly, chances are you'll always need six hours — give or take 30 minutes. However, as you age, you'll likely find that you sleep less soundly, meaning you'll need to spend more time in bed to get the same amount of sleep. By age 75, some people find that they're waking up several times each night.

Weight
As you age, maintaining a healthy weight — or losing weight if you're overweight — may be more difficult. Your metabolism generally slows, meaning that your body burns fewer calories. Calories that were once used to meet your daily energy needs instead are stored as fat. Your level of activity may decrease, resulting in unwanted weight gain.

Sexuality
With age, sexual needs, patterns and performance may change. Women's vaginas tend to shrink and narrow, and the walls become less elastic. Vaginal dryness is a problem. All of this can make sex painful.

Impotence becomes more common in men as they age. By the time they're 65, up to one in four men have difficulty getting or keeping an erection about one in every four times they have sex. In others, it may take longer to get an erection, and it may not be as firm as it used to be.

How long can you live?

The longest documented human life span is 122 years. Though a life span that long is rare, improvements in medicine, science and technology during the last century have helped more people live longer, healthier lives. If you were born in the early 1900s in the United States, your life expectancy was only about 50 years. Today it's around 77.

And if you're sure you've already done too much damage to yourself to hope for a long life, think again. Researchers say it's never too late to adopt a healthy lifestyle. For example, if you quit smoking now, your risk of heart disease begins to fall almost immediately. Living a healthy lifestyle can improve how you age. Eating a variety of fruits and vegetables and getting out for a daily walk are ways you can begin preparing now for your later years.

HOME REMEDIES For Whitening Teeth

HOME REMEDIES

Finally, there are the various and rather dubious home remedies for whitening teeth:

Brushing with lemon juice.

Don't. Lemon juice can lighten the color of your teeth, but only at the expense of your teeth. The juice is acidic. It causes calcium loss. This whitens teeth because calcium gives teeth some of their off-white color. It also means affected teeth are less resistant to decay and cavities. Your teeth might be brighter, but you could have fewer of them.

Brushing with mashed-up strawberries.

Another ill-advised idea. The notion here is that the strawberries' fibrous pulp and seeds act as scrubbers, scraping away nasty plaque and germs. But the fruit's sugars and acids do more harm than good, requiring that you immediately and thoroughly brush with a fluoride toothpaste.

Brushing with baking soda.

This doesn't really whiten teeth — there's no bleaching action — but baking soda can help remove plaque and make teeth shiny because it's abrasive. Use too much baking soda too often, however, and you may damage the enamel of your teeth.

Brushing with wood ash.

Wood ash (presumably retrieved from your fireplace) does whiten teeth because it contains potassium hydroxide, otherwise known as lye. But the ash has to come from a hardwood, such as oak, maple or walnut. Ash from softwoods like pine don't contain enough potassium hydroxide to be effective.

Again, be careful. Wood ash may contain other chemicals and compounds you wouldn't want to put in your mouth. Also there's no way to know how much potassium hydroxide you're actually getting in a dab of wood ash; too much too often can significantly damage your teeth.

Tips For Whiter & Brighter Teeth

Smiling Through Brighter, Whiter Teeth

Your smile is one of the first things most people notice about you. Unfortunately, as we age, teeth can become stained or grow darker and present a less than brilliant picture to the world. There are many reasons why your teeth may not be the bright white you’d like them to be.

Some medications can cause discoloration in your teeth. Coffee, tea and certain foods can stain your teeth, and smoking will also cause yellowing of teeth, as well as having other more serious side effects to your health. Also, as you age, the outer layer of your tooth enamel is worn away, revealing the darker tissue underneath.

The first step in your search for a brilliant smile is to discover what’s caused your teeth to become discolored. Your dentist can determine the cause of discoloration, whether tooth whitening can help, and which kind of whitening procedures will be most effective.

Not all whiteners work the same way, and not all whitening products will help your smile. For instance, in general, yellowish teeth bleach well, while brown or gray toned teeth usually do not. Also, tooth whitening products will not affect bondings or fillings, so porcelain veneers or bondings, so that all your teeth will be the same color, might be best for you. Once you’ve discovered the cause of your tooth discoloration, there are several options available, from over-the-counter products to the latest in dental applications using lasers.

All toothpastes help remove surface stains, and some whitening toothpastes contain polishing or chemical agents that provide additional stain removal. But whitening toothpastes only remove surface stains. Whitening toothpastes can lighten your teeth by about one shade, while your dentist can help you go three to eight shades lighter.

Similarly, over-the-counter whitening strips and gels cannot achieve the degree of whiteness that your dentist’s products can. The concentration of hydrogen peroxide isn’t as high in over-the-counter products. Worse, many kits have acetic or citric acid as the lightening agent, which can cause damage to your tooth enamel if overused or used improperly.

The safest, easiest and most sure way to whiten your teeth is to have your dentist prescribe the best method for you, whether it’s in-office bleaching, at-home bleaching, or whitening toothpastes. Most in-office or at-home professional methods use either carbamide peroxide or hydrogen peroxide as a bleaching agent. Impressions are taken of your teeth, from which custom trays are fabricated. You place whitening gel into the tray and ‘wear’ the tray on your teeth. The length of time can vary greatly, depending on the condition of your teeth and your body’s response to the bleaching agent.
