  1. Wonder if anybody checked the grammar in the study..!!
    Whatcha wanna bet???

    People who don’t care about grammar don’t like to be corrected…that’s why they never bothered to learn correct grammar!

    1. The sense of smell is often taken for granted, that is until it deteriorates. As we get older, our olfactory function declines.1,2 Not only do we lose our sense of smell, we lose our ability to discriminate between smells. It has been reported that more than 75% of people over the age of 80 years have evidence of major olfactory impairment, and that olfaction declines considerably after the seventh decade.1 A more recent study found that 62.5% of 80 to 97 year olds had an olfactory impairment.3 However, it is widely accepted that taste disorders are far less prevalent than olfactory losses with age.4

      There are numerous theories on why the sense of smell deteriorates as we age, I shall attempt to outline a few of these. Various anatomical and physiological theories have been presented. We are aware that both the number of fibres in the olfactory bulb, along with olfactory receptors decrease noticeably with age.1 The bulb losses may well be secondary to sensory cell loss in the olfactory mucosa, along with a general deterioration in central nervous system cognitive processing functions. Even in the absence of disease, olfactory receptor neurones undergo apoptosis at a baseline rate in each person. Mammals have the ability to replace these cells, however this process degenerates with ageing.5


  2. “…however this process degenerates with ageing.”

    Along with everything else….
    Getting old is no piece of cake, but it beats the alternative!!
