I did a little experiment tonight. I rode an exercise bike while watching the State of the Union Address to see how many Calories I could burn during the speech. I don't get political very often (I don't dislike politics, but I do tend to dislike politicians. They annoy me), but I do try to watch every State of the Union Address.
Anyways, I jumped on my recently purchased Schwinn 213 recumbent bike and started peddling. I set the bike program to "Pikes Peak." This wasn't such a good idea. The program starts out at "ahhh, what a nice ride" and over the course of an hour, ramps up the resistance to "kill me now!" Thankfully, Bush is no Clinton. A 90 minute address would have killed me. Bush's 50 minute address was just about right.
When all was said and done, the computer told me I had spent 337 Calories of energy (that's about 1400 kJ). From now on, this is how I will measure all State of the Union Addresses.
