Thanks for the wonderful read, Sarah! A question out of curiosity. Objects in Nature, to the best of my knowledge, are symmetric and operable by humans with the same behaviour-of-hand (rocks, leaves, branches of tree, waves, sea-shells etc) i.e. We as right-handed or left-handed work with nature pretty much the same way. Is there any field within Ergonomics that takes into consideration study of nature in terms of this operational symmetry and design products much the same way instead of specifics for Left-handed humans?
