London, Sept. 18 -- : The findings of a new study suggest that humans do not need to think in order to walk efficiently because they can adapt automatically.

The findings of the study were published in the 'Journal of Experimental Biology'.

Whether sauntering beside a lake or clambering a mountain, humans adjust their strides to make sure that they consume the least energy possible.
