So, fun fact. I've recently come to terms with an ugly fact : I have a legitimate physical addiction to caffeine. If I go a full day without, I get headaches by the end of the day.
Hardly the worst withdrawal symptoms ever, and defeated by some motrin and water ... but still, a bit upsetting. Now if you'll excuse me, I need to indulge my habit
For this reason, I included caffeine tablets in my 72-hour earthquake survival kit. I don't want to be fighting caffeine withdrawl at the same time I'm searching for shelter. I don't trust Starbucks to have emergency power and water plus enough beans in-stock to feed my addition in case of disaster.
That's smart. I'm addicted to caffeine (taken in coffee form) as well, but it's not that hard to break. I've done it a couple times, once voluntarily; more recently when I had the flu and lost all taste for coffee (only took a couple days to get back).
The abuse of this particular substance doesn't amount to much, and there are benefits, so I'm not particularly worried. I might be a little crabby for the first couple days of the apocalypse.
Re the Keurig - they're just looking for revenue streams post-K-cup-patent-expiration. I predict this approach will fail, when competing manufacturers continue to make cheap coffee makers compatible with the massive selection of currently-available cheap K-cups. I love our Keurig, but it's already made coffee stupidly simple; there's just no need for anything better.
