Japan's Rail Workers Pointing at Things (2017)
The book I'm reading currently 'modular habits' uses the Japanese train conductors usage of this finger pointing an example of how to reinforce habits - the accident reduction noted with this technique was quite significant.On another note - how strange is it when you learn something new of which you haven't known about your whole life only to several days later see it appear on hn.. is there a name for this sort of thing?
