ok so i have been looking around for some information about organic food expiry dates and the whole "does being in the dark improve your senses" idea.
i found two websites that mentioned organic milks have a longer expiry date to normal milk. however, they said the reason for this was not because it is organic but because of the way it is heated to kill bacteria (pasteurisation). so that wasn't exactly very helpful.
the sites are:

http://www.greencuisineorganics.com/organic-milk/does-anyone-know-why-organic-milk-has-such-a-long-expiration-date
and yes i looked on yahoo answers too...

with the senses idea, i found lots more good info. but all of the articles i found were about blind people's senses. most of them agreed that blind people have more acute senses compared to sighted people. i wonder if there would still be a slight increase in senses after sitting in darkness, where there are no visuals to distract you????
the articles i read are:
