Yeah, but the artificially purified 100% caffeine stuff? That'll kill 
ya. ;-)

Not a lot of people seem to know this, but caffeine is actually an 
insecticide. That is why the tea tree manufactures it. To kill insects.

There's a widely-circulated photo on the Internet where they fed spiders 
with different drugs to see what would happen to their webs. And 
caffeine had the most drastic effect. At which point everybody flips out 
like "OMG, we drink this stuff!" But humans aren't the target. The fact 
that caffeine has *any* effect on humans at all is mere coincidence; 
it's *designed* to incapacitate insects, who have a very different 
nervous system to our own. Spiders are a lot more similar to insects 
than mammals...
