how to boil a frog?

"The Boiled Frog"

They say that if you put a frog into a pot of boiling water,
it will leap out right away to escape the danger.

But, if you put a frog in a kettle that is filled with water that is cool and pleasant,
and then you gradually heat the kettle until it starts boiling,
the frog will not become aware of the threat until it is too late.
The frog's survival instincts are geared towards detecting sudden changes.

The story's origins are rooted in nineteenth-century physiological literature. It is actually based on many experiment done in 1987, one at John Hopkins University.

This is a story that is used to illustrate how people might get themselves into terrible trouble.

This parable is often used to illustrate how humans have to be careful to watch slowly changing trends in the environment, not just the sudden changes. Its a warning to keep us paying attention not just to obvious threats but to more slowly developing ones.

The story has been reprinted many times and used to illustrate many different points, including: inaction toward global warming and corruption as a system.

Unfortunately, there no story or findings about how to save a boiled frogs. In a brief observation, when we're trying to save Indonesian frog, which had been boiled for 33 years, by suddenly taken them out of the boiling pan in order to save them, they tend to jump back to it. Perhaps they felt cold. And when the people who boiled them die, the mourned for 7 days.

do we have to do it slowly?
