EVERYDAY SCIENCE

Detailed explanation-1: -Today, technology allows us to optimize our health on an individual basis improving personal life expectancy. We now have affordable access to diagnostic tools such as gene sequencing and wearable health-tracking devices. We use diagnostic tools to inform decision-making practices on an individual healthcare basis.

Detailed explanation-2: -While average life expectancy (the number of years a person can expect to live) is relatively easy to calculate, maximum lifespan estimates (the greatest age a human could possibly reach) are much harder to make. Previous studies have placed this limit close to 140 years of age.

Detailed explanation-3: -For example, a baby born in the US in 2021 has an estimated life expectancy of about 76 years, according to the latest report from the National Center for Health Statistics. Our life expectancy varies depending on our current age, sex, race and ethnicity, and where in the US we live.

Detailed explanation-4: -Life expectancy for men and women A male child born in the United States today will live to be 74.5 years old on average. This puts the male citizens of the US in 47th place in this ranking. On average, US women are 5.7 years older, reaching an age of 80.2.
