Your biological age can provide a good clue about your longevity, far more so than your chronological age. Your biological age refers to the state of your cells — they can be younger or older than your calendar age, which means you’re aging slower or faster than expected.
Environmental exposures have a lot to do with biological or cellular aging and, according to a December 2019 study1,2 published in The Journals of Gerontology, lead, mercury and perfluorooctanesulfonic acid (PFOS) are the three toxins shown to have the greatest impact on your life span.
While glyphosate was not included in this study, my guess is it would probably be a top contender as well, considering it disrupts normal body functions, especially your gut, and appears to enhance the damaging effects of other toxins.
According to Stephanie Seneff, Ph.D., a research scientist at the Massachusetts Institute of Technology, glyphosate worsens virtually all modern diseases which, of course, will shorten your life. That said, lead, mercury and PFOS have repeatedly been identified as significant contributors to chronic ill health and are certainly among the most pervasive and concerning toxins out there.
