I’m going out on a limb by saying this, but one thing about human bodies that we could all probably do without is excessively sweating. How many perfectly white tees are going to have stained armpits for it to come to an end?
And while even trivial things like sweating through our shirts are less than ideal, it also doesn’t help that the products used to stop our sweating come tucked in packaging that hurts our planet more than it helps.
