Gap between life expectancy and life span.

Life expectancy differs from life span. Life expectancy is an average for the population, including those who die shortly after birth, in early adulthood and late in life. In contrast, life span is a specifically individual concept, and thus, the maximum life span is an upper bound value rather than an average value.

However, these two terms are often confused with each other; people often take a statement like "the life expectancy was 39 years" to mean that the people of that time or place had a short maximum life span. In actuality, life expectancy is a statistical measure of the average time an organism is expected to live, based on the year of their birth, their current age and other demographic factors including sex.

Owing to improvements in Korean's congenital blood pressure than populations in Western countries, as well as in health care systems, medical technology and dietary habits, life expectancy has increased, and the may likely to become the first to have a life expectancy will exceed 90 years by 2030. According to a study published in The Lancet that used statistical models for aging populations, Korean women will be living the longest by 2030. Women born in Korea can expect to live, on average, to nearly 91 years, and their male counterparts to 84 years, the highest life expectancies in the world for the sexes. By 2030, Korean women will likely dethrone their Japanese counterparts as the world's longest living population. But even today, Koreans are expected to live to as long as 82.4 years, nearly four years longer than American, because Korea is very equitable, all the way across the population.

According to the Korea Statistical Service, in 2016, the life expectancy in Korea is 79.3 years for men, 85.4 years for women and 82.4 overall, much higher than the OECD averages of 77.9 years, 83.2 years and 80.6 years, respectively. These figures place Korea fourth out of 35 OECD member countries in terms of women's life expectancy, following Japan, Spain and France. In contrast, the life span in Korea is 64.7 years for men, 65.2 years for women and 65 years overall, indicating a gap between life expectancy and life span of 14.6 years for men, 17.2 years for women and 15.9 overall. It means the decreasing quality of life by spending a considerable period of time with ailing or disable mental or physical situation as destined. The long period of unstable plant-like status for any aged is meaningless at all.

Desirable life habits are necessary to narrow the gap between life expectancy and life span for the entire human population. To have a good quality of life, we need energy, vitality, alertness and a pain-free existence, but these criteria are not always easy to fulfill owing to daily fatigue and worries that plague us. However, it is clear that an adequate diet, simple exercising regimen and moderate sleep help strengthen our bodies by stimulating our muscles and bones, burning calories and reducing our weight. Life is short, and time is swift. Before we know it, life is already half-spent. In other words, one hour today is worth two tomorrow. Even for senior citizens in their twilight years, something that is well done is better than something that is well understood, regardless of whether the gap between life expectancy and life span is narrows or broadens.
