On this, our 317th Evolutionary Lens livestream, we discuss radiation and its impact on (rodent) health, and the 9th circuit’s decision to let men use women’s spas. First: research published in 2018 finds that low levels of non-ionizing radiation—like that emitted by cell phones and air pods—are actually associated with life extension in mice and rats. Don’t get too excited—these are the same rodents whose breeding protocols have broken them in some counter-intuitive ways, including that low doses of toxins or radiation can actually slow down the cancer that will otherwise kill them. Then: Olympus Spa, a traditional Korean nude spa for women in the Seattle area, was told by the state of Washington, now upheld by the 9th Circuit Court of Appeals, that they must let men in, so long as those men think they’re women. Judge VanDyke’s dissent correctly summarizes the issue as one of “swinging dicks.”
