Women's cunning

In the Middle Ages in one of the French towns, women used to get a diluted poison that they put in the man's food in the morning, and upon his return they gave him an antidote at the beginning of the night, and this poison did not affect the man but rather! In the event that he does not return home and stays in another place, he is late in obtaining the antidote, and the man suffers from headache, nausea, shortness of breath, depression and pain, and the longer the man is absent from his condition. The greater the effect of the poison, and when he returns home, his wife gives him the antidote. Unbeknownst to him, his condition improved within minutes, and this trick fooled the man, imagining that being away from home causes him pain, depression, and nausea, so he becomes more attached to his home and his wife.
