Humans Age At Remarkably Different Rates.

reports in “Science Now” that “humans age at remarkably different rates, and that we start aging earlier than one might guess,” according to a study published July 6 in the Proceedings of the National Academy of Sciences. The 954-participant study also revealed that “young adults already showing signs of aging aren’t just prematurely old; they seem to be getting older faster than” other people. study participants were “taking part in a lifelong medical study since they were born at a hospital in Dunedin, New Zealand in 1972 and 1973.” Investigators “came up with a batch of 18 measurements they believe correlate with aging,” including “medical measures of their lungs, their kidneys, their livers, their hearts, their immune system and even the integrity of their DNA.” that at age 38, participants’ “‘biological age’ – the state of their organs, immune system, heart health and chromosomes – ranged from as young as 30 to as old as 60.” People whose biological age was older even looked older. In addition, “the fast-agers showed worse balance and poorer motor coordination, and reported having more trouble with tasks such as climbing stairs or carrying groceries.” Recognizing accelerated aging early may also cast light on some of the earliest influences on aging: genes, prenatal circumstances, childhood experiences and socioeconomic influences. http://www.latimes.com/science/sciencenow/la-sci-sn-old-young-biomarkers-20150706-story.html
