Ask HN: What's a mind-blowing fact you know?

That HN is turning into reddit with posts that don't contribute to the startups, tech, engineering, entrepreneurship, or science topics that its contributors used to focus on.

You can drink snake venom without being harmed (provided you have no ulcers or cuts in your mouth). Stomach acid will break down the proteins in the venom so they no longer have impact.

Don't know if that's the kind of fact you're going for, but now you know.
