So then, any effort spent educating oneself and preparing right now probably won't be wasted. It's like buying honey for your pantry: it doesn't expire, and you know you will use eventually.
 

But knowledge can in fact "expire", it can be lost, e.g. when it isn't used, when there's no repetition for long periods of time.
