The human nose is an underrated tool.Humans are often thought to be insensitive smellers compared with animals,1 this is largely because,2 animals,we stand upright.This means that our noses are 3 to perceiving those smells which float through the air,4 the majority of smells which stick to surfaces.In fact5,we are extremely sensitive to smells,6 we do not generally realize it.Our noses are capable of 7 human smells even when these are 8 to far below one part in one million.Strangely,some people find that they can smell one type of flower but not another,9 others are sensitive to the smells of both flowers.This may be because some people do not have the genes necessary to generate 10 smell receptors in the nose.These receptors are the cells which sense smells and send 11 to the brain.However,it has been found that even people insensitive to a certain smell 12 can suddenly become sensitive to it when 13 to it often enough. The explanation for insensitivity to smell seems to be that brain finds it 14 to keep all smell receptors working all the time but can 15 new receptors if necessary.This may 16 explain why we are not usually sensitive to our own smells we simply do not need to be.We are not 17 of the usual smell of our own house but we 18 new smells when we visit someone else's.The brain finds it best to keep smell receptors 19 for unfamiliar and emergency signals 20 the smell of smoke,which might indicate the danger of fire.

Finding ways to 10 this growing homeless population has become increasingly difficult.11 when homeless individuals manage to find a 12 that will give them three meals a day and a place to sleep at night,a good number still spend the bulk of each day 13 the street.Part of the problem is that many homeless adults are addicted to alcohol or drugs.And a significant number of the homeless have serious mental disorders.Many others,14 not addicted or mentally ill,simply lack the everyday 15 skills needed to turn their lives 16.Boston Globe reporter Chris Reedy notes that the situation will improve only when there are 17 programs that address the many needs of the homeless.18 Edward Zlotkowski,director of community service at Bentley College in Massachusetts,19 it.\has to be 20 of programs.What we need is a package deal.\
