German medics have apparently advised people walking on icy streets to adopt the gait of penguins to avoid slipping (https://www.theguardian.com/world/2017/jan/04/penguin-walk-german-doctors-advice-slipping-icy-paths). Humans hold their centre of gravity equally between the front and rear legs whereas the bird keeps it on the front leg and is much less likely to slip. I shall continue my daily shuffle around the mean streets.
