If you were an actor and you wanted act the part of an aged person. Apart from the make up , and dress you would develope the walk that most aged people have. That is you would walk without lifting the heel of the standing foot from the floor. which in turn can make the head bent over and be too far forward. So if you don't want to dance like an aged person learn at what point the heel leaves the floor of the standing leg and where the moving leg should be at that time. What happens with an aged person is after a while the muscles used in walking correctly stop working.If you don't use it you lose it
That is another advantage that dancing correctly has. Once a walk is learnt correctly I doubt if it will ever get lost.
