Whilst on one of my numerous workouts, my gaze fell on the noticeboard. There was a poster up, advertising a class, with the date/time printed on it. Underneath the headline, there was a caption saying "It's good for your CV". Brilliant, I thought - if I go to this one, they'll help me put my curriculum vitae together and then I'll be far more employable. This is amazing - exercising and improving my job prospects in one.
I was absolutely delighted with this, and rushed off after my session to tell my lovely young man of my exciting discovery. He looked at me sympathetically, (but I think there was pity there too), and told me that CV, this instance, means cardiovascular. What a t*thead I am. There is a moral to this - if you think something's too good to be true, then it probably is.
