The Travelling Sales Problem and 'how to get fitter and more coordinated'

"Simple" walking; why are some persons so uncoordinated and some seemingly naturally graceful at just walking? Two ten year old boys, one comes from a sporty family that does many different seasonal activities, and enrolls the kids into appropriate organized activities and sports, as well as providing quality housing that is situated in safe, abundant parks and even forests close by. The other child is in an apartment in a busy downtown of Hong Kong, having a family that emphasizes studies for future professional life, and neglects sports and physical activities.

The first child, from 200 meters away is seen to walk confidently, almost like a wild animal such as a cheetah. The other is timid and awkward and even stiff.

The kinesiologist has insights into what makes a robust, confident athlete, and what causes poorer outcomes with children.

They might list 3 essential elements to consider. Maybe 5. What about 10? Surely the more pertinent detail the more sophisticated the process and effectiveness?

Generally, as the Travelling Sales Problem suggests, the more towns to visit, the more possible routes to try to establish the best sequence of town visits. A few towns seems manageable. 10 towns goes into tens of thousands. 15 millions. Get the idea? Things get unwieldy very fast, so it is best to establish essential factors if possible. This explains why AI and apps rely on algorithms, to sort out the most relevant inputs.

What about the senior citizen who is about to become frail and prone to falls? How might they be walking, and how might the kinesiologist identify the most important factors to 'solve the problems', i.e., a safe, effective and confident gait or walking method?

Consider the importance of finding a qualified professional when you need sophisticated help?!
