People watching on holiday and noticed the vast number of slightly larger ladies and some teenagers whose legs sort of crank outwards below the knees. Usually associated with thick knees and shapeless legs. Gives a waddle as they walk from the knees possibly due to the thighs rubbing. Some men as well. Got talking to the wife and we remembered that at the schools the nusrse would see us once a year and our gait was looked at - perhaps as a sign of something serious. I reckon some of these odd gaits are going to cause serious medical conditions due to knee wear. From a mechanical perspective a straight leg is going to be the strongest.
I wonder if the medical profession take any interest in this?
