Scientists Show Human Aging Rates Vary Widely 285

HughPickens.com writes: Ever notice at your high school reunions how some classmates look ten years older than everybody else — and some look ten years younger. Now BBC reports that a study of people born within a year of each other has uncovered a huge gulf in the speed at which human bodies bodies age. The report tracked traits such as weight, kidney function and gum health and found that some of the 38-year-olds in the study were aging so badly that their "biological age" was on the cusp of retirement. "They look rough, they look lacking in vitality," says Prof Terrie Moffitt. The study says some people had almost stopped aging during the period of the study, while others were gaining nearly three years of biological age for every twelve months that passed. "Any area of life where we currently use chronological age is faulty, if we knew more about biological age we could be more fair and egalitarian," says Moffitt. The researchers studied aging in 954 young humans, the Dunedin Study birth cohort, tracking multiple biomarkers across three time points spanning their third and fourth decades of life. They developed and validated two methods by which aging can be measured in young adults, one cross-sectional and one longitudinal. According to Moffit the science of healthspan extension may be focused on the wrong end of the lifespan; rather than only studying old humans, geroscience should also study the young. "Eventually if we really want to slow the process of ageing to prevent the onset of disease we're going to have to intervene with young people."

It's precisely that kind of distorted talk that makes it clear that you and groups like Amnesty aren't really interested in anything but tearing down the West.And THAT sort of tactic IS exactly like that which was promoted by the Soviet Union (i.e. those evil communists).

And it happened there precisely because nobody spoke up against it when they still could have.

That's probably what the algorithm should return, just to avoid the possibility of offending anyone. Just label any photos of intelligent hirsute bipedal mammals as "Hominids" and call it a day.

Who knows, maybe the term will even catch on in the larger culture. "Machine learning" doesn't mean we can't learn from our machines.

For example, one must apply to the Ministry of Communication to be accepted into the UIC and the application form asks about membership in political organizations like the Communist Party or Young Communists League along with technical qualifications

From the article: "... Stallman submitted his application without citing any formal association with the Communist Party, but instead described his pioneering work with the FSF and authorship of the GPL. Unexpectedly, however, his application was declined. When asked to comment on Stallman's rejection, a UIC official responded, 'What kind of organization does he think this is? We're Communists, not a bunch of (expletive deleted) radical ideologues!'"
