I believe in it, My mum's ex husband tried to kill her on a number of occasions and later died of cancer. One of my mum's bosses made her life hell, she later died of cancer. My sisters (much older) boyfriend treat her like shit, he died in september... of cancer. When my dad was a teen he was bullied by this guy who rode a motorbike and one day he stepped over the line with my dad but he held himself back, the guy rode off into the sunset.... crashed his bike and died. It's kinda scary to think of it actually.
