Last week, my poo sticks arrived.
It's a test for bowel cancer; the kit includes six cardboard sticks, which you use to smear a small amount onto each of six places, two per day. It's not nice, but it's easy and it's a way to make an early diagnosis of something that would be a big problem. So I posted it off, and today I got the result.
I'll get the poo sticks kit again in two years.
