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.

5 steps to adapt your home as you age

Adapting a home to suit an older person’s needs can help him live there longer. This can be done with renovations, such hiring a contractor to widen doorways to accommodate wheelchairs, or lowering countertops and cabinets in the kitchen. It can also be done with simple fixes, such as switching round doorknobs to lever door handles that require only a push downward; rearranging a pantry so that food and cooking utensils are on lower shelves; or adding non-slip treads to bathroom floors and shower stalls.
