Do you feel that your colleague at work could do with a bit of cheering up? Why not set them an orange peel challenge? You could provide the oranges or get people to bring their own and have a competition at lunch time. See who can peel their orange so that the skin comes off in one long continuous spiral. You could have a winner for the longest spiral or a winner for who finishes first. A great way to get your colleagues to eat one of their 5-a-day too. Let us know how you get on.
