My research focus is on what happens to our immune system as we age. So the job of the immune system is to fight infections. It also protects us from viruses and from autoimmune diseases. We know that as we get older, it's easier for us to get infections. So older adults have more chances of falling ill. This is evidence that our immune system really doesn't function so well when we age. In most of our work, when we were looking at older adults who've got an illness, we always have to have health controls. So we work very closely with a great group of volunteers called the One Thousand Elders, these volunteers are all 65 or over but in good health. They come to the university to provide us with blood samples to be interviewed and to help us to carry out a whole range of research. The real impact of our research is going to be on health in old age. At the moment, we are living much longer. Life expectancy is increasing at 2 years for every decade, that means an extra 5 hours a day. I want to make sure that older adults are still able to enjoy their old age, and that they are not spending time in hospital with infections, feeling unwell and being generally weak. We want people to be healthy even when they are old.

我的研究重點是我們的免疫系統(tǒng)在隨著年齡的增長會發(fā)生什么變化。免疫系統(tǒng)負責對抗感染。它還能保護我們免受病毒和自身免疫性疾病的侵害。我們知道，隨著年齡的增長，我們更容易感染。所以老年人有更容易生病。這證明當我們變老時，我們的免疫系統(tǒng)確實不能很好地發(fā)揮作用。在我們的大部分工作中，當我們看到患有疾病的老年人時，我們總是必須對他們進行健康管理。因此，我們與一大群人組成的志愿者團體緊密合作，這個團體叫“千個老人”，這些志愿者都是65歲或65歲以上，但健康狀況良好。他們來這所大學是為了給我們提供接受預檢的血樣并幫助我們進行一系列的研究。我們研究的真正影響在于關注老年人的健康。目前，我們的壽命要比過去長得多。預期壽命是每10年就增加2年，這意味著每天增加5個小時。我想確保老年人仍然能夠享受他們的老年生活，并且他們不會因為感染、身體不適和普遍虛弱而在醫(yī)院呆上一段時間。我們希望人們即使在年老的時候也保持健康。
