People who get "hangry" share two genes linked to neuroticism and schizophrenia, new research from DNA-testing company 23andMe has revealed. Just yesterday, a psychological study on "hangriness" (a term coined for people who get particularly angry and irritable when they need to eat) found that the feeling doesn't just arise when hunger does, but depends almost entirely on one's emotional state. According to 23andMe's survey of 100,000 people, 75 percent of us get that "hangry" feeling at least occasionally. To the surprise of the research team, getting "hangry" actually had very little, genetically speaking, to do with metabolism.
