A Popular Mechanics article takes a look at what the near future holds in terms of upgrades for we humans; biomedical gerontologist Aubrey de Grey is one of the featured scientists: "There's a difference between working on aging and working on a specific age-related disease. Curing one age-related disease might extend life by five or 10 years, but an awful lot of people who would have died from it will die of something else instead. Even if we fix only four or five of these things very well, we probably won't get more than an extra 10 or 20 years of life because the things that we can't fix will still be accumulating. ... Depending on funding, it will take another 10 years or so to get to the proof-of-concept stage in the lab. I'd say we have a 50/50 chance getting these therapies all working in humans 15 years after that."
