Well, it is possible to overdose on caffeine and have a stroke, heart attack etc. It’s apparently happened to people consuming caffeine pills or powder. If you guzzled 14 cups of joe within the space of a couple hours, would you be close to that toxic level of caffeine? Maybe, but I suspect anyone guzzling that much coffee would suffer an upset stomach before they got into such dangerous territory.
I've taken up a new hobby -- collecting coffee beans from local roasters in our travels. I just picked up beans from roasters in Winthrop, WA; Whistler, BC; Revelstoke, BC; and Banff, AB (actually roasted in Calgary). I just had a cup of "Soledad" roasted by Good Earth in Calgary. It was really good - "Dark roast Guatemala, Brazil & Latin America."
It's a cheap, simple, and rewarding hobby. Plus, I get to renew my coffee supply as it runs out. It's an excuse for another trip!
My other cheap hobby is collecting baseball caps from our travels. I just got two from Jasper, AB. One is from Lake Maligne where we went canoeing in a stiff breeze...
We hit absolutely perfect late-summer / early fall weather before the snow flies. The tour boats were sold out, so we decided to go out in the canoe and I'm really glad we did. That was a LOT better than being on a powered cruise boat with endless narration for 90 minutes.
How's that for a seamless segue from trigonelline to a travelogue!?
