It's just a brain.
Not an expert. Nosy, though, and willing to do the reading.
There's a brain in my head and it doesn't work on what I ask it to. I'll be doing something entirely normal, putting the bins out, and it pipes up with: hang on, why is bin day the one appointment I have never once missed? And then it won't let it go.
That's the whole thing, really. ManBrain is a brain that gets stuck on something, goes off and finds out about it, then makes me write it down so it can move on to the next one. Sending it to other people on a Friday was its idea too.
Some weeks it lands on something useful, like what the numbers on a drill mean, or why everyone has suddenly started eating protein. Some weeks it lands on why every house has a drawer of cables nobody can identify and nobody will throw out. It doesn't take requests as such, though you're welcome to try.
I'm not qualified in any of this, which I reckon helps. I can still remember what it was like to not know, because I didn't know last Tuesday. It's written by a bloke and it sounds like one. That's the only entry requirement and it isn't enforced.
It's one brain and one question a week. There isn't a bigger plan.
