How would the world/society change if every human had deadly, venomous fangs?

Haha I didn't consider how much more dangerous that profession becomes in this world.

but would provide a lot more thrill...

I got removed for trying to add conditions to the question but I was kind of thinking you would be immune to your own venom. I presume snakes and other animals are; I also originally suggested maybe there are like a 1000 species of human so your not immune to everyone else necessarily and don't know who could kill you.

But yeah otherwise bite your lip, bite the dust. It would at least stop me from biting my nails though, maybe.
