Want to sign up for a massive human experiment? Too late. You’re already a lab rat. There was no ethics approval or informed consent. You weren’t asked, you never signed up, and now there’s no easy way to opt out. We don’t want to be alarmist. We’re not suggesting you’re about to sprout wings, grow coarse hairs in surprising places and become a gruesome half-insect like the Brundlefly (the side effects of real life scientific experiments rarely impress like the special effects in David Cronenberg’s film The Fly).
