Elderly Challenge - Observation 3

As you can see in this video, the elderly man is having problems walking as he is moving with a shuffling gait, step by step. He cannot walk big steps.

Later, he ascends the steps pretty quickly, although not as fast as a normal person.

I feel that such elderly people can do quite well for themselves, but there are other elderly that have much more serious mobility problems than this senior. We must therefore help these much more physically challenged elderly, being much more mobile than them.
