Cold = good ~ here's why...

Cold weather can be good for you. I did a little research on this recently when I observed that the tulips in my apartment this week when it was very cold lasted two weeks vs. the one week during the warmer summer months.  Many of my friends tease me that I could keep pet penguins in my home during the winter months since I don't use the heat. They can laugh but there are a few distinct advantages to not turning on the crazy inefficient electric heater. Then I read this article and it supports how I feel about it. My mitochondria are getting a workout, especially when riding the motorcycle in these temps like this morning (see below) but it's not all so extreme thanks to heated hand grips and electric vests.
