The trend of the past is the result of medicine and medical development that did not in any way attempt to address the causes of aging. Benefits have resulted from either (a) inadvertently slowing down the damage accumulation, or (b) compensating in some way without addressing the damage. In either case the benefits are small in the grand scheme of things. 0.1 years of life expectancy at 60 with every passing decade is not a large outcome, and we should not be surprised to find it small given that treating aging as a medical condition hasn't been the goal of research or implementation. Trying to keep a damaged machine running without repairing the damage is expensive and futile. How far does changing the oil in a car or pressing the accelerator harder get you if you never fix anything that goes wrong in the engine? Similar situation. The future will be radically different because researchers are now resolved to treat aging as a medical condition, to investigate the causes, and to intervene. The debate now is over the best way to go about it, and alas most of the research community remains fixated on the path that will cost a great deal and achieve next to nothing, which is to say efforts to alter the operation of metabolism so as to modestly slow down the aging process. Calorie restriction mimetics, autophagy enhancement, and etc. If you want better results, you have to look to the rejuvenation research of the sort carried out by the SENS Research Foundation, the Big Pharma groups clearing amyloid, the new senescent cell clearance startups, etc. Slowing aging by altering metabolism is the expensive road to nowhere. Repairing the causes of aging is the more efficient, faster road to rejuvenation of the old and the prevention of aging.
