Given the average age of our readership (more on that in a future edition), this seems appropriate. A study reported by the BBC found that sex is a very rare trigger for cardiac arrest. Only 34 out of the 4,557 instances of cardiac arrest examined were associated with sex. And of those, 32 were men, mostly middle-aged. (No, men, you may not use this increased risk to explain the earnings gap.) Disturbingly, CPR was found to have been performed in only about a third of the cases. Maybe the other two-thirds just figured they fell asleep? But seriously, if you don’t know how to perform CPR, here’s a guide. It can save a life. And preserve a sexual partner.
