Innovation in Aging, 2018 The close inverse relationship between male and female height and life expectancy. By Samaras T, Marson S, & Lillis J. Abstract Many papers have provided reasons for why women live longer than men. These include XX vs. XY chromosomes, sex hormones, and better care of their health. In addition, males experience more deaths from homicides and risky behavior. These factors certainly can affect male and female health, but none has been proven to explain the actual […]

Abstract Samaras Thomas T. Why Smaller Humans are in our Future. Policy Innovation, Carnegie Council 10/20/2014 Evidence for “Less is More” in relation to the human body In nature, when animals get big, their numbers decline to match the resources available.  Humans are violating this biological rule by producing not only larger beings but more of them. Since larger people (taller and heavier) require much more of virtually everything, we are aggravating resource, food, and water shortages, and accelerating environmental […]

Abstract Numerous Western studies have shown a negative correlation between height and cardiovascular disease. However, these correlations do not prove causation. This review provides a variety of studies showing short people have little to no cardiovascular disease. When shorter people are compared to taller people, a number of biological mechanisms evolve favoring shorter people, including reduced telomere shortening, lower atrial fibrillation, higher heart pumping efficiency, lower DNA damage, lower risk of blood clots, lower left ventricular hypertrophy and superior blood […]

Important Publications Many papers have provided reasons for why women live longer than men. These include XX vs. XY chromosomes, sex hormones, and better care of their health. These factors certainly can affect male and female health, but none of these factors has been proven to explain the actual difference that exists in life expectancy between the sexes. However, a factor commonly ignored is the size difference between men and women. Past research has shown that differences in male and […]

Journal of the World Health Nutrition Association, Volume 3, Number 2, March 2011 Commentary. Human growth, height, size: Reasons to be small Thomas T. Samaras [Abstract] This paper warns of the worldwide dangers related to increasing growth and body size. Samaras explores the impact of increasing body size on performance, intelligence, the environment, resource consumption, and fiscal costs. Numerous examples of his findings are illustrated.

Chronic obstructive pulmonary disease is responsible for 126,000 deaths per year. A large Harvard study found that good nutrition can help you avoid this disease. For example, fruits, vegetables, whole grains and fish promote healthy lungs and reduce the risk. In contrast, refined grains, red meat, and cured meats increase the risk.Source: Harvard Men’s Health Watch, 2010, vol 14, No. 7, pp 1-3.
