For me it means not everything can be prevented, and sometimes whatever bad can happen, happen. It's out of our control. We just need to handle those in our control and predict the probability of uncontrollable one, and whether we can accept those risks (probability * severity). Edit: and that's why coronavirus is so devastating to businesses. Primarily because it's probability is so small with high severity and it's out of our control. * On a side note, I really have thought about it once, that my ex boss's diet is so horrible I'm afraid he will caught a disease. Thankfully it didn't happened in my 4 years of working there.
