I just recently happened upon an interesting website called EnergyFiend.com. Pretty straightforward in its purpose, Energy Fiend offers a calculator of just how many servings of your choice caffeinated beverages it would take to kill you (based on your weight only -- so, clearly it's not an exact science, but interesting, nonetheless). For example, if you weighed 175 pounds, it would take consuming approximately 45 Starbucks tall coffees in one sitting to kill you.

It's kind of fun, in a strange and slightly macabre sort of way. But, it also lead me to uncover some interesting facts about how much caffeine is in some products, many of which I didn't expect to rank so high. For example, I was rather surprised to discover that many fruit-flavored sodas are relatively high in caffeine. And, I also was amazed at the fact that the aforementioned Starbucks tall coffee actually contains more caffeine than a dose of Maximum Strength No-Doze pills.

The jury is still out on whether or not caffeine is healthy (I've read opposing views on this matter), but the one thing that is for sure is that too much of anything -- be it caffeine or, well, anything else -- is not a good thing. Therefore, you should try to limit your caffeine intake to 250mg per day, which is about what you'll find in an average (read: Non-Starbucks) cup of coffee.
