The scientific study of old age — how the body, the mind, and daily life change as people grow old, and how societies care for that. It is a university and research word, not everyday chat.

The scientific study of old age這是對老年的科學研究 how the body, the mind, and daily life change as people grow old探討身體、心理和日常生活隨著人變老而有什麼改變 and how societies care for that以及社會如何照顧這些變化 It is a university and research word這是大學和研究用語 not everyday chat不是日常聊天會用的字

Doctors who treat older patients are doing geriatrics; gerontology is wider than medicine, though the two sit next to each other and people mix them up. You hear it in news about ageing countries, pension plans, and ‘how to grow old well.’ Though actually, some speakers stretch it to mean ‘anything about old people,’ which is looser than the -ology really allows: this is a field of study, not a polite synonym for old age itself.

Doctors who treat older patients are doing geriatrics治療年長病人的醫生做的是geriatrics（老年醫學） gerontology is wider than medicinegerontology比醫學更廣 though the two sit next to each other and people mix them up不過兩者關係密切，人們常把它們搞混 You hear it in news about ageing countries, pension plans你會在關於人口老化、退休金計畫的新聞裡聽到它 and “how to grow old well”以及「如何優雅變老」的新聞裡 Though actually不過其實 some speakers stretch it to mean “anything about old people”有些人把它延伸用來指「任何跟老人有關的事」 which is looser than the -ology really allows這比-ology這個字尾真正允許的範圍還要鬆散 this is a field of study它是一門學科 not a polite synonym for old age itself不是「老年」這個詞本身的委婉說法
