My office currently has a load of fundraising chocolates for sale. If I take the stairs to make a purchase (rather than go via the lift), have I earned it? I hate to think how many flights of stairs I’d need to climb to burn the kilojoules in a big Freddo frog.

A colleague reassured me that I burn kilojoules going downstairs again. Thanks for that, but I suspect I’d need the chockies to be further than 1 flight of stairs away.

Eat an apple instead? Or maybe only one almond would cover it?

What the hell – life’s for living right?
