This is the hard data on incidence of specific diseases for the year 1995 and (projected) 2025. I have omitted chronic diseases as a group, although they are projected to increase from 90 million (1995) to 168 million by 2025.
The confluence of aggravators work too well together: quality of life, disposable income, percentage of those depressed, number of those with multimorbidities, and the fact that the incidence shows no signs of stopping.
We may be looking at a snowball effect: If the workforce is undergoing constant depletion and is being increasingly transformed into a burden, the economy will start to shrink, and this will hasten the process of depletion of the remaining workforce. Access to health care will begin to decrease, further hastening disintegration of health, economy and living standards.
I think it is abundantly clear looking at the chart below that life expectancy has no chance of increasing by 2025, but the question is how much will it decrease and how quickly?
And also: what forces exist to help mitigate the damage?
