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."

A marketing term that really means 'the time before everything hurts,' promising you can avoid turning into a creaky old hypothesis faster than you can say 'confounding variables.' "Until there’s a randomized control trial on Healthspan that doesn’t just use mice, I’ll treat it like Loch Ness: possibly intriguing but mostly speculative science fiction."

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!"
