Is there french man been eating glass and metal since 1959?

Yes, a Frenchman named Michel Lotito, also known as "Monsieur Mangetout," gained fame for his unusual ability to eat non-food items, including glass and metal, starting in the late 1950s. He consumed various materials and was known for his performances, where he would eat bicycles, televisions, and other metallic objects. Lotito's unique practice was attributed to a rare condition that allowed him to ingest these items without harm. He continued this unusual diet until his death in 2007.
