I’ve slipped a disc again, and for extra fun I’ve managed to do something to the sciatic nerve so there’s pain in my leg that isn’t actually real (it’s referred pain from the nerve) and that doesn’t respond to things like heat patches. It’s seriously bloody sore, and yet again I’m thanking myself for spending silly money on a ridiculous chair: where beds, sofas and dining chairs are all painful to sit at, my posh chair leaves me pain-free.

If you’re interested and flush it’s a Herman Miller Mirra, which I’ve seen online for around £375. That sounds like a lot but if you have back problems, you’ll get much more benefit from that £400ish quid than you will from a new smartphone or iPad. I’ve had this one for years, and it’s as good today as it was when I bought it.
