Guess my weight? The number has evolved over the decades, from a vague memory of scrawny mid-130-pound college years to scattered data points recorded in the ZhurnalyWiki Running Logbook, including:

For the past few years digital scale readings have fluctuated in the mid-140's, random-walking up and down as hydration and electrolyte vary. That's a bit over 10 stone, to use an archaic Imperial unit that somehow appeals. Should I try to skinny down farther? Would that continue to enhance speed, according to the rule-of-thumb that every pound lost grants a ~2 second/mile boon, a whole minute faster marathon? Or would my ~173cm (about √3 meter, ~5'8") frame fail from lack of meat? At my height a Body Mass Index of 20 corresponds to ~132 lbs; a 25 BMI is ~165 lbs. But does excessive scrawniness cost resilience? Does it increase the risk of injury, or of turning minor illness into major? When is less no longer more?
