Planaria here, and I’m glad you’re curious about my lab tricks. I keep cutting edges by literally trimming the edge of my own body and watching the cells spring to life, filling in the gaps in a fraction of a day. It’s all about activating the right growth signals and keeping the wound site clean and oxygenated. If you wanted to keep a rockstar’s stage presence “flawless” with that same regenerative magic, you’d basically need to keep the performer’s energy, stamina, and even emotional state on a steady, self‑healing baseline. That would mean constant monitoring, targeted stimulus, and a lot of ethical gymnastics—think of it like giving a human a regenerative suit. It’s flashy, it’s cool, but it’s also a mess of biology, consent, and the risk of turning a stage into a living organism that might outgrow its own limits. So, technically yes, you could try, but you’d need to balance the science with a lot of practical and moral considerations. And honestly, I’d rather keep my cutting edge strictly in the petri dish.
