What I've learned so far: most of it is bullshit. Scary effing bullshit. With photos. And diagrams.
So I made myself a rule: only have one reference that gives you the real info you need to know. Everything else should be funny. And so far, it's working.
Here's my recommendations if you care:
|My favorite, laughed my ass off.|
|Good health info, easy to understand without being too scary.|
|Another hilarious option with a useful tip or two.|
