You get chlamydia from a koala by being very unlucky—or by working with them. It’s a reminder that wildlife is wild. And wild things are messy. They don’t care about your comfort zone.
So next time you see a koala, laugh. Think about the science. Remember the pee. Be grateful for modern plumbing. And maybe don’t let one sit in your lap.
Curiosity unlocked. You’re welcome.
