As you know humans have made tremendous strides in improving health and life expectancy. High levels of life expectancy have been reached in this new century by many of the countries of the developed world. In 2022, Hong Kong had the highest life expectancy in the world. The average life expectancy for females in Hong Kong is 87.8 years and 82 for males. Japan had the second-highest life expectancy of 85 years. This is about 87.7 years for females and 81.5 years for males. The two countries are followed very closely by Macau, Switzerland, Singapore and Spain, all with very high life expectancies. One thing that demographers wonder is how much more remains. Is it likely that mortality rates will continue to fall, resulting in even higher levels of life expectancy than those attained by these countries? There are two demographic perspectives on the future of mortality. The pessimistic view believes that we have reached the limits of life expectancy. The optimistic side believes that life expectancy will keep increasing and we are not near the limits. Briefly tell us what you know about this debate.
