I always take some of that anti-bacteria hand wash stuff with me, especially when I use public transport. Also in the winter if I go into London for any reason, I keep my gloves on whenever I use the tube/train.
I think it’s time we copied the Japanese. If you have a cold/flu wear a face mask and gloves. Start bowing to each other instead of shaking hands, or air-kissing. If you’re not well stay at home. Don’t struggle in to the meeting so you can give everyone else your infection. It’s beginning to really annoy me, the British habit of trying to just ignore being ill.
More on topic, maybe we need their high tech toilets with water jets as well!
