But this isn't the past - this is now in the middle of a pandemic where guidelines are clear as a bell (at times when Government pays attention to its medical & scientific advisors). Wash hands frequently, carry hankies or tissues if you need to cough, sneeze or blow your nose, avoid touching your face and sanitise your hands if you must (in the absence of hand-washing facilities). So carry hand-sanitiser and tissues or hankies, ready to use, in your voluminous anorak pockets or your great big luminous yellow or Green jacket. Simplez.
