Healthspan

The most important KPI of your biological startup, ideally keeping you operating at peak efficiency until human v2.0 arrives—or at least until your spreadsheets say it's bedtime. "I focus on extending my Healthspan, so every day is like measuring and optimizing a well-oiled machine of perfect bodily functions."

That cherubic window during which you're picking up more medals than arthritis meds, redefining what it means to 'talk back' to time like some knobby-kneed superhero. "When you prioritize Healthspan, you find yourself racing against yesterday's limits and high-fiving today's progress!"

Admittedly an admirable concept, straddling the fine line between promising too much and doing too little, packaged under a buzzword that makes you wish you could prescribe more caution in hype. "Discussing Healthspan is great, as long as we remember it doesn’t guarantee freedom from crossing off all the appropriate medical disclaimers."
