Anything is better than doing what you have to do?

Here's what i did when i was studying for one of my finals thats coming up in about 12 hours...

I modeled the cooling for my A/C and cost for running it... cause its an old model kenmore, so i was lazy to look online for it... and i just had to procrastinate... now i ll shall kick myself in the butt back to work , sigh... feeling crappy a lil...anyways have fun...
