@b0rk I am 45 and there's a number of things I've never gotten round to learning: like spelling "beauraucracy" or whatever that word is for stuff with too much paperwork. Or which side port and starboard are (I did briefly know this, but I didn't use it so I forgot). Or how to use that Linux "ip" command, almost all the network config I do happens on BSD machines. I'll learn things when I need to. Only worth learning things sooner if they're interesting or something!
