Males born in the Lesotho have the lowest life expectancy of the world in 2022. Similarly low is the life expectancy for females born in this country. The average woman lives only 56 years.
Provisional data from 2021 show that overall life expectancy across all racial/ethnic groups was 76.1 years (Figure 14). Life expectancy for Black people was only 70.8 years compared to 76.4 years for White people and 77.7 years for Hispanic people.
In 2020, the U.S., which substantially outspent its peers, had the lowest life expectancy, and Japan, the country with the lowest per person health spending, had the highest life expectancy among similarly large and wealthy nations.
Males born in San Marino or Monaco had the highest life expectancy in the world as of 2022. San Marino also had the highest life expectancy for females with on average 89 years. In Japan the life expectancy was 88 years for females and 82 years for males.
Japanese life expectancy
This low mortality is mainly attributable to a low rate of obesity, low consumption of red meat, and high consumption of fish and plant foods such as soybeans and tea. In Japan, the obesity rate is low (4.8% for men and 3.7% for women).
While females have both X chromosomes in the 23rd pair, males have one X and one Y chromosome. The Y chromosome has fewer genes than chromosome X and is linked to some chronic diseases. This makes men have a higher mortality rate.
People with Down syndrome can expect to live to 60
In the 1940s, a child with Down syndrome had a life expectancy of 12 years. These days, their life expectancy is 60 years and a baby born with Down syndrome could live into their 80s — in line with the general population.

This study showed that children's anthropometric traits predicted their parents' longevity better in the case of mothers than fathers. Mothers of small-bodied children and fathers of vigorous sons had higher chances of becoming longevous.
ADHD can reduce life expectancy by as much as 13 years, but its risk is reversible.
Most individuals with Down syndrome have mild (IQ: 50–69) or moderate (IQ: 35–50) intellectual disability with some cases having severe (IQ: 20–35) difficulties. Those with mosaic Down syndrome typically have IQ scores 10–30 points higher than that.
Married men and married women live, on average, two years longer than their unmarried counterparts. One reason for this longevity benefit is the influence of marital partners on healthy behaviors. Study after study shows that married people eat better and are less likely to smoke and drink excessively.
Visceral fat is a risk factor for coronary heart disease, the leading underlying cause of death for Australian men. Coronary heart disease, which results from a combination of biological factors and lifestyle habits, is a major reason for the difference in mortality between men and women.
In the United States, the average male is about 5 feet 9 inches tall. 1 Factors like genetics, nutrition, and medical conditions can affect where you'll stand on the growth charts.
Eating well, not drinking too much alcohol, avoiding tobacco, and staying physically active enable some individuals to attain a healthy old age; genetics then appears to play a progressively important role in keeping individuals healthy as they age into their eighties and beyond.
U.S. life expectancy at birth
On average, a person living in the U.S. can expect to live to 76.1 years. Asian people have the longest average life expectancy (83.5 years) and American Indian/Alaska Natives the shortest (65.2 years).
1. Monaco. One of the smallest countries in the world, Monaco also has the UN's longest estimated life expectancy of any country as of 2023.
Life expectancy is a statistical measure of the average time someone is expected to live, based on the year of their birth, current age and other demographic factors including their sex.
However, there is no clear link between ADHD and IQ. A person may have a high, average, or low IQ score and also have ADHD. ADHD may cause a person to interrupt in class or perform poorly on tests. This can cause other people to believe that they may have a lower IQ.
People with Down syndrome usually have an IQ (a measure of intelligence) in the mildly-to-moderately low range and are slower to speak than other children. Some common physical features of Down syndrome include: A flattened face, especially the bridge of the nose. Almond-shaped eyes that slant up.
His performance beats those of physicists Stephen Hawking and Albert Einstein, who were both estimated to have IQs around 160.
