Question: what are the chances of you dying on your birthday?
Answer: A 2012 study in the journal Annals of Epidemiology found a much higher probability (about 14 percent) that people over 60 will die on their birthdays. That study, which analyzed more than 2 million deaths, found that strokes and heart attacks rose 18.6 percent and 21.5 percent, respectively, on birthdays.
