The things I don't know

Sometimes I’m surprised by the things that I don't know. It’s interesting that you can live for 28 years and not know about simple things that other people consider common knowledge.

For instance:
I am a total caffeine addict. I can’t function after 9am unless I’ve had my morning coffee, and a 3pm coffee gets me through those last, slow two hours of work. It’s been like that since I was about 18. So if we do a little bit of nerdy maths, we can estimate that I’ve drunk roughly 7300 cups of coffee in the last 10 years. About half of those would have been instant coffee, the other half barista made coffee.

And yet, after 7300 cups of coffee, I only discovered the existence of this nifty little doo-dad today:

It plugs up the hole in your coffee cup lid so that you don’t spill coffee all over your car! How is it that in 10 years of solid coffee drinking, I’ve never come across this before? And why is it that every single person I’ve told about it alredy knew they existed?

It amazes me. It also makes me wonder what other things everyone else knows that I don’t.
