Just came across this finding & we can take a lot of cues form this in our life. Like a frog we all react when there is instant change / impact in life and we ignore slow change / impact in life.
If the temperature of the water is suddenly increased, the frog realises it and jumps out of the water.
But if the temperature is very slowly increased, one degree at a time, the frog does not realise it till it boils to death.
