Aging

Children born today in the United States can expect to live nearly 78 years. That life expectancy is a great leap forward from 1900, when the average newborn couldn’t expect to reach age 50. Similar increases have been seen in in developed nations all around the world. In the 20th century, life expectancy increased more than it had in any century since the beginning of human civilization.

Life expectancy at various ages in teh United States

And the longer you live, the longer you can expect to live. Average life expectancy for a newborn American is 78 years, while it is 84 years for a 65-year-old and 87 years for a 75-year old.

But extending the lifespan has also increased the burden of diseases such as heart disease, stroke, cancer, arthritis, osteoporosis, macular degeneration, and other conditions that tend to affect older individuals. Most of these diseases, though, aren't inevitable consequences of aging. Instead, many are preventable.

Solid research from long-term studies such as the Framingham Heart Study, the Nurses' Health Study, and others have shown that the combination of not smoking, eating a healthy diet, exercising regularly, and keeping blood pressure, cholesterol, and blood sugar in check can prevent three-quarters or more of these chronic conditions.

Minding your memory

Most adults experience the occasional "senior moment" as they age. While these memory slips may be embarrassing and stressful, they are not always a warning sign of problems like Alzheimer’s disease or another form of dementia. Still, for specific types of everyday forgetfulness, adopting certain lifestyle behaviors and strategies can help people retain and recall information and navigate memory lapses when they arise.

Sound check on hearing aids

Approximately one in three people ages 65 to 74 has age-related hearing loss. Research continues to show that people with hearing loss who get fitted for hearing aids tend to be more active.

The power of protein

During his lifetime, a man loses about 30% of his muscle mass. Older men can maintain and even regain muscle by combining regular weight training and a proper diet, including adequate amounts of protein. Research suggests that to help counter lost muscle mass, healthy older adults need 1.2 grams of protein for every kilogram of body weight per day. This is calculated by dividing a person’s weight in pounds by 2.2 and then multiplying by 1.2. (Locked) More »
