One of the oldest clichés about marriage is “never go to bed angry” and it looks like there’s truth behind that! A new study out of London found that if you go to bed angry, you might NEVER get over the argument. When you sleep, your brain organizes your memories and stores them. So if you’re angry about something, it winds up being committed to memory, which makes it much harder to get over it in the future. (Photo: YouTube)
