The human nose is an underrated tool. Humans are often thought to be insensitive smellers compared with animals, 大1家 this is largely
because, 大2家animals, we stand upright. This means that our noses are
大3家 to perceiving those smells which float through the air, 大4家
the majority of smells which stick to surfaces. In fact, 大5家, we are extremely sensitive to smells, 大6家 we do not generally realize it.
Our noses are capable of 大7家 human smells even when these are 大8家
to far below one part in one million.
Strangely, some people find that they can smell one type of flower but not another, 大9家 others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate 大10家 smell receptors in the nose. These receptors are
the cells which sense smells and send 大11家 to the brain. However,
it has been found that even people insensitive to a certain smell 大12家
can suddenly become sensitive to it when 大13家 to it often enough.
The explanation for insensitivity to smell seems to be that the brain finds it 大14家 to keep all smell receptors working all the time but
can 大15家 new receptors if necessary. This may 大16家explain why we
are not usually sensitive to our own smells—we simply do not need to
be. We are not 大17 of the usual smell of our own house, but we 家
大18家 new smells when we visit someone else's. The brain finds it
best to keep smell receptors 大19家 for unfamiliar and emergency
signals 大20家 the smell of smoke, which might indicate the danger of
fire.
