Ever been in a queue and felt somebody was a bit too close? Personal space is all about boundaries, but did you know that the acceptable space is different in every culture? There are two kinds of cultures – “contact” and “non-contact”. Non-contact cultures keep their distance (That is places like Asia, North America and Northern Europe), while contact cultures are the exact opposite. In India, people pack in to trains and even queues, while in Japan, people stand at an arm’s length! Why is that? Researchers suggest that climate, age, and gender have an effect on personal space.
