Why do we all know what to do if we ever encounter a bear?
Think about the things we are taught as children.
"Wash your hands before you eat."
"Look both ways before crossing the street."
"Play dead when you're being attacked by a bear."
All of these are good pieces of advice (unless it's a one-way street and then you just look silly), but some are more relevant than others.
I'm never gonna meet a bear, and if I do, I'm probably already in big trouble. That's just useless information taking up space in my mind.
Why do I need to know what to do if a bear attacks? I don't know what I would do if I won the lottery, and that's much more likely. From now on, I will spend my time thinking about how to spend my winnings instead.
