It is challenging to think of such low risks: when we have to count the zeros, all intuition goes. So what else has roughly a one in 100,000 chance for a young adult? We could choose from the risk of dying when under general anaesthesia, or in a
skydiving jump, or, on the positive side, winning the
Lotto jackpot if you bought 450 tickets, or guessing the last five digits of someone’s mobile phone number.
Perhaps more pertinently, it’s roughly the risk of a young woman on the
contraceptive pill having some form of blood clot in one week.
