So…
For anyone who wondered about such things I can confirm that even hypoallergenic connectors for heart monitors leave a hideous and itchy rash. I have a big red welt from yesterday’s one, which I had to swap and reposition a day early because in my sleep it was making me wake up thinking I was being strangled.
I look as though I’m wearing a radio mic unless you look at my chest, and most people don’t appear to do that (which bashes a myth or three). So I’m considering it practise for the future 
Other issues. I have comprehensively concluded that I really don’t understand other human beings. Y’know that Katy Perry song (no, not the one that’s guaranteed to annoy Max), Hot n’ Cold. I’m guessing, on account of the fact that all my regular readers have what might be regarded as better musical taste than me, that you won’t all be totally familiar with the lyrics. But take a guess and I’ll bet you’re pretty near (if you really can’t imagine then the lyrics are here). I think some people are confused, which is fair enough, but some people should maybe deal with that in their time rather than confusing other human beings too. Who would maybe like to know what the devil is going on, and that if it involves them, perhaps their permission/opinion might be sought first. Oh and the bus thing happened again. Weirdo .
I am unilaterally crap at quadratic equations, and am having to redo something that’s GCSE level. And not for the thing I thought I’d got wrong. Which is both disheartening and reassuring all at once!
Despite a smattering of experience, I will never understand menfolks. I thought they were always hot and cold, in and out, up and down and whatever else that dear Ms Perry chooses to sing about (when she’s not out asking girls if she can borrow their Chapstick).
I was awful at maths GCSE, and whatever persuaded me to try it at A Level soon evaporated. I salute you.
