Caf­feine is impor­tant to the pro­duc­tiv­ity of geeks. Well, of any­one, I sup­pose. I had a wicked caf­feine addic­tion that I man­aged to kick by trav­el­ling in Europe for 3 weeks in 2008. The com­bi­na­tion of not being able to get good cof­fee, hang­ing out with peo­ple who didn’t have an urgent need to caf­feinate in the first two hours after wak­ing, hav­ing my sleep­ing pat­terns destroyed by jet lag and keep­ing odd hours meant that the need to fix was gone when I got back into my nor­mal surroundings.

Then, we got an espresso machine in the house/office. Wel­come back, caf­feine addic­tion my old friend.

So each per­son knows how much cof­fee they need to func­tion… but how much does it take to kill you?

For­tu­nately, some­one took the time to do the math and made a handy tool for the rest of us to use. Sim­ply choose your region, enter your weight, select your caf­feine source of choice and click to find out what it will take to put you down.
