I was doing an interview with a female enigineer named Susan and took her into Harvey’s office for him to meet her. During the interview, Susan developed hiccuos. Harvey said he could help her. He gave her a glass of water and he told her to drink the whole thing down as he put his finger over her ears to block them. She did it and the hiccups stopped. Ever since then everyone who gets hiccups that I helped is cured by this neat technique. Try it.
