Fountain of youth

Worse than a corporate scam since its a human scam. There is no fountain of youth, not everybody has the gift of being an eternal child, some people do and some don't. You could convince people that everybody could be that way, but not everybody is good at being charming or childlike and playful, just like any talent, not everybody has it.

People who tell you there's a fountain of youth must think you can't handle the truth.
