Grey Matter

So, today I went to Health and Wellness class and had my body composition measured. It was done using a method involving electrical impedance. Basically the device sends an electrical signal through my skin and then measures the resulting current to determine the amount of body fat I have. This method is not very accurate. I ended up getting a -4.1% reading. Technically speaking, it is not possible to have a negative percentage of body fat. The real question is why the engineers of this device even allow it to generate negative percentages. It should just display an error message and instruct you to repeat the measurement process. Continuing on, I went ahead and calculated my body fat in pure poundage using a positive version of the previously mentioned percentage. I weigh around 165. 165 * 0.041 = 6.765. In essence, less than 7 of my 165 pounds are fat. The lowest percentage recommended for me was 5% body fat. So, 165 * 0.05 = 8.25 pounds. I need to gain 1.485 pounds of fat to be at the minumum recommended healthy body fat percentage. One pound of fat is approximately 3000 Calories. 1.485 * 3000 = 4455. One Calorie is equal to 4.184 Joules of energy. 4455 * 4.184 = 18639.72. A Joule is equal to the amount of energy measured as one amp of electrical current passing through an electrical circuit with one ohm of resistance in one second. In other words, one watt-second. A 100-watt bulb uses 100 watts per second. (18639.72 / 100) / 60 = 3.10662. That small amount of fat that I need to gain to be "healthy" is enough energy to light a 100-watt light bulb for over 3 minutes. In conclusion, I took this way too far...

Also, I got my Physics "exam" back. I missed one question which resulted in a score of 92%. I was immediately miffed, but then I realized that I spent approximately 0 minutes actually studying for this test. It is okay.

In Biology today, no one in the class knew how E. Coli was transmitted. I got to say "fecal matter" aloud in class. Then I was asked to explain how poop gets into our food. People looked at me like I was a freak, which was flattering. I bet, judging be the looks on some of their faces, that most of them go home and totally overcook any meat they eat tonight out of fear.

I'm done.
