"The proportion of people aged 65 or over is forecast to reach nearly 40% of the population in 2060" This takes for granted that in year 2060 people will be old like they are today. That change in human biology won't happen. One of the areas our company has worked is DNA(software) processing. You probably have heard about "mother cells" for a reason. Those things could do incredible things. They repair the body constantly(if you are young),when you lose them, you age. Breakthroughs on this area wont probably happen in single years time. But over decades it is a different story. This will create another problem for humanity(humanity has always solved problems by creating new [smaller]ones). But at the same time we will have fusion and ability to travel (cheaply)outside the earth by 2060.
