Most of human history has been blighted by poor survival rates among children, and that continues in various countries today. It is also true that improved healthcare and treatments have also increased the number of years, on average, in which people live with a given disease burden or disability. Epidemiologists and gerontologists such as S. Jay Olshanky warn that in the United Stateswhere two-thirds of the population is overweight or obeseobesity and its complications, like diabetes,could very well reduce life expectancy at all ages in the first half of 21st century.
