Found myself in an interesting conversation this morning in my hotel. I am leading a tour group at the moment and someone was talking about achilles tendon problems. A woman, one of our guests, spoke up and said, matter of factly 'Men can't do this of course, but women can wear heels to ease the strain on the tendon." To which I replied, just as matter of factly: "Men can do that." She gave a start and spluttered, "Well ... I ... I ... suppose they could ..."
I left it at that.
