I drink four or more large glasses of soda or iced tea at lunch (I pee right after lunch and about 30 minutes later like clockwork).
At 2PM, I go to the local Starbucks with my co-worker Randy. Where he orders his usual and I pointing to his order and say "I'll have a Randy as well, but with WHIP on top." The employees laugh as they proceed to make two venti Java Chip fraps with +7 espresso shots, one with the whip crème mixed in and the other with it on top (This drink costs more than my lunch). The drinks are gone before we walk the block back to the office.
Then around 6:30PM after most people have left, I make four cups of coffee and spit it with the girl who works late in the office next to me, I make 6 if Randy is still there. (I poop and drive home)
My heart rate is generally between 98 and 110 beats per minute given the amount of caffeine I consume. My brother who does not drink caffeine, same weight, same height, has a heart rate of 36-40 bpm.
