As we age, it's not unusual to need reading glasses and hearing aids as our senses wane. But a surprising study has now claimed that losing your sense of smell when you're older could mean that your time is nigh.
Scientists from Rush University Medical Center in Chicago found that the more everyday odours a person can identify, the more likely they are to be alive several years later. The team gave more than 1,000 volunteers, aged between 53 and 100, a standard 12-item smell test.
Study leader Dr Robert Wilson told Mail Online: 'We used a scratch and sniff test for each odour where the participant had a choice of four options.The odours were fairly familiar such as smoke, lemon, black pepper, chocolate and cinnamon.'
The researchers then followed the participants, none of whom had dementia or Parkinson's disease at the time, for four years.
