Climbing the stairs was made redundant by escalators and elevators. Now why a machine has been invented to simulate an activity rendered obsolete by escalators by elevators? Wouldn't climbing the steps have served the purpose?

There are some people to whom the physical act of walking is painful...climbing stairs is impossible. There are people in wheelchairs who cannot climb stairs as well. There are mothers with strollers and young children..have you ever tried to climb stairs pushing a stroller? Jim and I choose to climb stairs for the exercise. It is our choice. Others don't have the luxury. It is for them that escalators and elevators are a godsend! :)

Hi Suby...Thought you might enjoy this pic of an escalator outside a gym. http://lh5.ggpht.com/_IogZb6c5nko/SBnZEXJyM0I/AAAAAAAABeo/4anL8iJzFSc/Only+in+America+-+Gym+Escalators.jpg
