I was driving-up I-25, thinking about my forthcoming trip to Ecuador when I noticed a truck carrying liquid nitrogen. As I was reading all the printed material on the back, I observed a sign that read “Venting is Normal”. Ironic, don’t you think? After all, at −346 °F, liquid Nitrogen is one of the coolest products out there. It’s so cool that if you put any organic matter in it (vegetable or animal), it freezes solid and can be shattered like glass. The last thing you would expect liquid nitrogen to do is to lose its cool and vent! Then again, maybe there is a life-lesson there for all of us. Maybe the reason liquid nitrogen is so cool (when it’s not venting) is that it doesn’t bottle-up all its feelings and that it allows itself to let it all out from time-to-time. Maybe we can even extend this life lesson to our diets. The lesson being that no matter how strict our diet, we need to leave a little room for a guilty pleasure (like a donut). Maybe not. In any event, they’re here so come and get one!
