Altered State

Humanity is being stewed... but the damage is gradual and hardly perceptible. Just like FROG STEW, the frog doesn't know he's gonna get cooked when he jumped in that pot of water, because it starts out nice and cool. But slowly and steadily the lethal process occurs. If he were thrown into boiling water, he'd jump right out, quickly aware of the deadly danger. But instead, as the temperature keeps rising, he is comfortably adapted to each new and changing degree until slowly he loses all consciousness, and before he even knows what's happening, it's too late, he's Frog Stew!
