I only sleep when I don't do anything, so I slept in jail: Salman

During a podcast with his nephew Arhaan Khan, actor Salman Khan said he doesn't understand what people mean when they say they can't sleep. Adding that he usually sleeps one or two hours, he further said, "Once a month I sleep for 7-8 hours...places where I can't do anything, like when I was in jail, I slept."
