Reading practice on life expectancy
What is longevity?
Longevity is determined by a variety of factors including location, relationship, genetics, lifestyle, environment and socioeconomic status. During the past few centuries, average life expectancy has increased globally and average life expectancy at birth is now 78.8 years in the United States. Some estimates place the maximum possible human lifespan between 120 and 150 years old, however this upper limit has not yet been achieved with the oldest-living people reaching around 120 years old.

Going out and longevity
For older people, getting out of the house regularly may contribute to a longer life – and the effect is independent of medical problems or mobility issues, according to new research.
“The simple act of getting out of the house every day propels people into engagement with the world,” said lead author Dr. Jeremy Jacobs in a phone interview.
“We saw similar benefits that you’d expect from treating blood pressure or cholesterol with medicine,” Jacobs said. “Social factors are important in the process of aging.”

Life expectancy and physical exercise
Exercise provides a remarkable variety of health benefits, which range from strengthening bones to positive effects on mood and helping to prevent chronic illnesses such as diabetes and heart disease. Research dating back to the late 1980s has consistently shown that aerobic fitness may help extend lives. Yet a few studies on athletes examining whether habitual vigorous exercise might harm the heart made some experts wonder how hard people ought to push when exercising.

Life expectancy and socialization
Research about an unusually long-living population on the island of Sardinia, Italy has showed that strong ties to family and friends, along with frequent physical activity, may contribute to their longevity, according to a May 9, 2019 article. This article also mentioned a recent review of 148 studies that found that people who are isolated face a 50% greater risk of premature death than those who have stronger social connections.
