Genetic material is funny. On the one hand, it's as personal and private as things can get. Your DNA is basically you. But on the other hand, it's also the most public thing about you. It's a biological equivalent of an open, unencrypted radio broadcast. You leave it absolutely everywhere all the time - you can actually imagine a mist of your genetic material floating behind you as you walk around. Dead skin cells, hair, whatever you excreted through sweat - you leave it on everything you touch or otherwise interact with, be it public or private property, or other people.

I'm having trouble reconciling those two views and developing intuitions around how we should handle it.
