Back in college, my friends laughed at the notion of colon irrigation. Have you heard of this? It’s basically a regimen the cleans your bowels from the inside, flushing out accumulated waste. It seems to be a fringe thing, but there are facilities devoted to making you squeaky clean. Ian Belcher, journalist with The Guardian went to one on assignment, sceptical at the beginning. After seeing what came out (his photographer released a marble he’d swallowed some twenty-two years earlier), he’s now a convert. I must admit… I’d like to go through the program myself.
