In nature, some individuals possess potent toxins within their bodies yet remain unaffected by their own poison, instead being able to harm other organisms. This phenomenon is perplexing and has become an unsolved mystery in history.
In Pittsburgh, USA, a worker named Grant developed an adaptation to cyanide after prolonged exposure. Remarkably, when he was bitten by a rattlesnake, he emerged unscathed while the snake perished. What physiological mechanisms lie behind this?
In Uttar Pradesh, India, a middle-aged man caused a venomous snake to die after frequently consuming cannabis. Even more astonishing, some dare to swallow live snakes; one such individual is South Africa's Lezzi V. Galeni, who, under medical supervision, can ingest various venomous snakes and even produce toxins capable of killing others with his bite. The existence of these 'poisonous people' challenges humanity's understanding of life's limits.
To this day, the secrets behind these 'poisonous people' remain largely uncovered, awaiting further scientific exploration.
