At Scientific American, Ray Kurzweil opines on the prospects for reprogramming our biology for far greater healthy longevity: "We are now beginning to understand biology as a set of information processes, and we're developing realistic models and simulations of how the processes involved in disease and aging progress. Moreover, we are developing the tools to reprogram them. ... Human life expectancy was only 37 years in 1800. Such technologies as sanitation, antibiotics, and other medical advances have more than doubled it in 200 years. Our ability to reprogram the information processes of biology will dramatically increase it again, but this progression will be much faster because of the inherent acceleration of information technology. I expect that within 15 years, we'll be adding more than a year each year to remaining life expectancy. So my advice is: take care of yourself the old-fashioned way for a while longer and you may get to experience the remarkable century ahead."
