We all might know individuals who lack awareness to the unpleasantness of body odors. But it seems like in certain cultures it's the norm rather than the exception.
I don't have any personal experience, and it might have changed, but in the past I've heard that in Russia (and Ukraine et al) it is the norm to shower once a week (not sure about use of deodorants).
Recent travels through IST airport exposed me to extremely unpleasant odors coming from the personnel doing the extra security check and pat down at the gate on flights to the US or TLV. The most recent experience was so bad that the entire gate area was intolerable.
I have also heard from friends who have been to Delhi, that theres a constant stench there.
What's up with these people? Do they have some kind of desensitized sense of smell? Is it at all acceptable coming from people in an official position in an international airport, which IINM is one of the top 10 for the number of passengers going through?
