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 found that having difficulty identifying familiar smells in old age could be associated with an increased risk of death
我们日渐衰老，器官功能慢慢衰退，很自然地，老花镜和助听器成为了必需品。但是，近日一项研究表明，当你步入老年，失去嗅觉可能意味着命数将尽。科学家发现，老年人无法识别曾经熟知的气味的话，增加了死亡风险。
Scientists from Rush University Medical Center in Chicago found the more everyday odours a person could identify the more likely they were to be alive several years later. The team gave more than 1,000 volunteers a standard 12 item smell test and then followed them for four years. None of them had dementia or Parkinson's disease. During this period 321 individuals or 27.6 per cent died.Amazingly, they found that the risk of death was 36 per cent higher for those who only got six of the answers correct compared to those who managed to identify 11 out of 12.This association was true even when disability, depression, brain dysfunction and leisure activity was taken into account.

来自俄罗斯驻芝加哥医疗中心的科学家发现，如果一个人能识别更多的气味，更有可能比其他人多活几年。研究团队对1000个志愿者进行了长达四年的研究，让他们分别12种气味标本。四年间，321人（占27.6%）死亡。他们中嗅觉分别率低的人（仅能识别一半气味）比嗅觉灵敏（12种气味中11种气味都能识别）的死亡风险高出36%。为体现科学性，参与研究的志愿者无一人和帕金森等疑难杂病有关。
Writing in January's edition of the journal Chemical Senses, Dr Robert Wilson and his team wrote: 'The results indicate that difficulty identifying familiar odors in old age is associated with increased risk of death.'
研究报告发表于一月份的期刊《化学感觉》中，其中医生Dr Robert Wilson如下写道：“研究结果证实了，老年人中无法识别曾经熟知的气味，死亡风险更高。气味识别能力和寿命有着紧密联系。
