If you had early signs of paralysis and you were really good at asking personal questions, you might figure out that this paralysis someone has is from syphilis, in which case you could give this nice concoction of mercury and arsenic -- as long as you didn't overdose them and kill them.
Se fossem sinais iniciais de paralisia e fossem mesmo bons  a fazer perguntas pessoais, podiam deduzir que essa paralisia  era causada pela sífilis e, por isso, podiam dar  uma agradável mistura de mercúrio e arsénico — desde que não exagerassem  na quantidade que matasse.
