In Sad Men, I explore my love of prawn advertising, and reveal that in order to keep up with prawn-related happenings, I have set up a Google Alert. Recently, it brought me disturbing news. Tiny quantities of anti-depressants flushed down our sinks and toilets are having a dramatic effect on the behaviour of my favorite crustaceans.

Maybe I could use this new-found information next time I get a brief for an ad about chilled prawns.

I’ll get my coat.
