A Wrigley's Airwaves gum claims to 'refresh your mind', but it may excite your bowels instead. The gum brand prides itself on giving an extra kick compared to the average chewing gum. Often tasting like throat lozenges, the brand has proved extremely popular in this polluted land of ours, where everyone wheezes and coughs. Now it has added an even more intriguing flavour called Fire. A Post colleague, who is not known for sharing many things, took one bite and immediately offered to give it away. I won't repeat his comments, which may invite a lawsuit. The food label on the back (pictured) of the Fire pack warns people not to take too much of the stuff. Otherwise, you'll be refreshing something else as well as your mind.
