It is also telling everyone that environmental changes are sometimes invisible. We should always be vigilant, keep a sober attitude, study more, don't always stay in the comfort zone, and exchange it for not being eliminated.
Boil frogs in warm water Source:
"Boiling frogs in warm water" comes from a "frog boiling experiment" conducted by scientists at Cornell University in the United States at the end of 19. When scientists put the frog into water (not boiled water) at 40 degrees Celsius, the frog couldn't stand the sudden high temperature stimulation and immediately jumped out of the boiled water to escape successfully.
When the researchers first put the frog in a container filled with cold water, and then slowly heated it (rising by 0.2 degrees Celsius per minute), the result was different. On the contrary, frogs are comfortable in the water, because the water temperature is comfortable at first. The frog found that he couldn't stand the high temperature, but he was unable to do so, and he was boiled to death by hot water before he knew it.
