Such a pain is it not Deja ? and we can't expect very many to really comprehend the alienation ... Gas stoves, extra showers because we have little idea of how we might 'smell' hour to hour, people wanting you to 'taste this' ... not knowing how careful we've become to just putting anything in our mouths. Reading canned food expiration dates is like a hobby to me now ! .... worse is that 'burning' sensation that alerts me to when I've entered an area that is reeking with strong paint or gasoline or carbon monoxide exhaust or a floor that has been mopped with near straight bleach ... we know we're near something vaporous but have no idea of the danger level or what fumes they are from ... Thank God for the added support job that tastebuds provide so without aroma assistance we can at least always know sugar, salt, citrus, bitter such as beer, and what the japanese (or is it chinese ) refer to as 'Umami'
