On beach holidays as a child I would stand at the edge of the sea and watch as the tide washed out around my feet. I loved the feeling of moving backwards when I was actually standing still.

Tango they say is a discipline that you can investigate for the rest of your life. And if you standstill, you get the feeling you’re moving backwards. Just like on the seashore.

A new series of Strictly Come Dancing is due to start on the BBC tonight. And no doubt this year, as in previous years, the programme will serve up its own particular version of Argentine tango.

It’s that time of year again. After the excesses of the festive period, there’ll be many of you out there thinking of putting on your tango shoes again and seeing how your first few steps feel.

Maybe a little wobbly?
