When you visit the page, the title is "How mud boosts your immune system" -- but isn't all the evidence and discussion about children? As far as I understand, this exposure to mud / bacteria is particularly beneficial during the first three years (maybe a few more years; probably not much consensus there) and there isn't evidence to think people over 18 would benefit from continued exposure (though gardening seems to benefit health; and perhaps those who have gone through antibiotic treatment might benefit - though I know of no such evidence, never looked). Could anyone who has more familiarity with the topic comment? :)
