So, I've been suffering with sore feet when I get up in the morning. Doesn't last. I hobble for a few minutes then its gone. But I looked on the internet and I read how it's quite a common complaint, and that a good cure is to roll a golf ball under your foot. I didn't get golf balls, instead I bought a couple of those super-bouncy balls that kids have that they bounce over your garden wall every few minutes.
So now when I write I do it in bare feet with a couple of these balls under my desk.
And Hey! Now I don't have sore feet in the morning.
They're sore all bloody day!
