When I was standing on the scales in my surgery today (I am a doctor), I noticed that the needle moved very slightly, exactly in time with my heartbeat. What could account for this fluctuation?

Rubbish collection seems complicated these days. Where I live, I use five different bins and the collections are fortnightly. Unlike many people I observe, I squash things like aluminium cans and plastic milk bottles. It seems logical and reduces the volume of rubbish stored in the house – but does doing so help collection and recycling?
