Fandom: Sherlock (BBC 2010)
Warnings: none
Notes: Prompt was "jet, heartbeat, and mathematics" for a 100 word drabble. I only got two of the three in double the word count, but I like it anyway.
Mathematics
Average heart rate of a healthy adult male approximately seventy beats per minute at rest. Personal average eighty-three when active, seventy-one when in meditation on the sofa, as at present. Estimated one-hundred-forty-five beats per minute during extreme physical exertion; generally high speed chases after criminals through the London streets. One-hundred-nine when in a heightened state, such as in response to immediate danger. (The heightened state is excitement, not fear, but this is irrelevant to Sherlock’s assessments.)
These are established normative values. Sherlock is trying to account for some recent deviations, to determine whether there is cause for concern regarding his physiological state.
He has been experiencing hikes of up to five beats per minute every time John calls him “amazing.” Average of ninety-one beats per minute during their non-stake-out dinners when John agrees to let him pay and doesn’t correct the wait staff who assume that they’re a couple. Such a heart rate makes no sense given the calmness and banality of the situation at hand. One-hundred-twenty-eight beats per minute when John is in danger, although that is logical as in such circumstances the odds of physical exertion and danger to Sherlock’s own life are significantly increased. He is more concerned about the abnormal knot that forms in the pit of his stomach.
Sherlock hisses in irritation and swings himself upright on the sofa, fingers still steepled together in front of his nose.
No matter how many calculations he runs, the math just doesn’t add up.
