Not keen to start the New Year with a cold or flu? Socialise mid-week, is the advice, when restaurants and cinemas are emptier. Public transport is another germ magnet, so if you rely on it, try travelling early (or late) so you’re not too close to someone who’s sneezing. And stick to air-kissing rather than shaking hands! (Without wanting to sound like Howard Hughes, we also carry anti-bacterial hand gels, too, and refresh regularly.)
