In a recent publication, researchers argue that there are flaws in past studies showing that, for the US population, wealth correlates with a sizeable increase in life expectancy. Those studies failed to consider the highly dynamic nature of wealth. Only a fraction of the population maintains a given level of wealth for decades: individual fortunes rise and fall quite rapidly. Taking this into account, the data actually shows that the size of the wealth effect for life expectancy is half of that previously estimated.
This is something of a distraction, however. The only real methodology by which wealth can be used to buy additional years of healthy life is to invest it into the right forms of medical research and development, meaning the establishment of rejuvenation therapies based on the SENS model of damage repair. Unfortunately all too few wealthy individuals have realized that this option is on the table. We can hope that this will change in the years ahead, as the first rejuvenation therapies worthy of the name make their way to the clinic.
New research results challenge previous findings of huge differences in life expectancy
