I didn’t state that “logic”. Per default I assume that everybody understands that we are talking about everything in moderation. Also I specifocally stated some boundaries in my original statement, ensuring the mental safety of children. I assume no parent in their right mind would push their child of a cliff to make it stronger. But parent let their kids test their physical limits by providing them with a safe environment (e.g. playground or backyard) and adult supervision.

When somebody states “stay hydrated” it is not only pedantic, but also somewhat schizophrenic to reply with "Drinking too much water too quickly you die, by that logic we should all gargle ourselfs to death, so your logic of staying hydrated is wrong. "
