Apparently if you have a teenage daughter in your house you will know what a "thigh gap" is.
A news item informed me that the latest body trend for our impressionable young girls is having a gap between your thighs when you stand with your feet together.
I was intrigued. Body obsessions are nothing new. People of all ages strive for the perfect body. However, when I looked on Facebook there were pictures of girls so skinny they looked terrible. One comment was "give those girls some food". Very sensible.
I asked around the office about thigh gaps. I got some very weird looks but one young lady of about 25 knew exactly what I was on about.
"I heard about that when I was at high school 10 years ago," she said. "It was like oh my god you've got a thigh gap ... you have the perfect body."
