Work is pretty evil as far as candy goes. I don't have to look very far for free, bottomless supplies of sweets. There are at least three places — no, make that four — at work that I can pick up some Sourheads®, some bite-sized chocolate bars, Twizzlers®, whatever. Forget the healthy stuff on my desk — sugar is what gets me going.
I'm going to postulate for a second here. I eat pretty much whatever's available to me. If I have a box of Stroopwafels, a pack of gum, a 2-liter of soda, or a six-pack of Saranac, I just consume it until it's gone. (Well, the beer I'll stop at three or so per day. Thank goodness my wife hides the beer and doles it out to me.)
Much like what NCN found, stuff that's just there gets eaten. No really good reason beyond that.
But on the bright side, I did do another 31 minutes on Wii Fit tonight, and got another perfect score on the soccer ball heading game. I found last night that I slept better after some exercise. Hopefully that will repeat tonight. 🙂
