However, it has been found that even people insensitive to a certain smell at first can suddenly become sensitive to it when 9 to it often enough.
The 10 for insensitivity to smell seems to be that brain finds it 11 to keep all smell receptors working all the time but can 12 new receptors if necessary.

We are not 13 of the usual smell of our own house but we 14 new smells when we visit someone else's. The brain finds it best to keep smell receptors _ 15 for unfamiliar and emergency signals such as the smell of smoke, which might indicate the danger of fire.
