I was interested to read here that people who sleep less tend to be fatter because disturbed sleep patterns affect their appetite. That's the gist of it anyway but then my eye strayed to another heading - "10 ways to burn off 100 calories." Two of those were:
walking briskly for 35 minutes
shopping for 35 minutes.
Well, no contest there! But the last one was the best of all:
Watch TV for one hour and 10 minutes!!!
Hands up who's for a brisk walk then!
