揭女人比男人長壽原因

Professor Tom Kirkwood of Newcastle University has come up with a new theory for why women live longer than men, the Daily Mail reports. Men are simply more biologically "disposable". The controversial study shows that the female body is better at carrying out routine maintenance and keeping the body's cells alive. The aging process is caused by tiny faults throughout our body. As faults build up, the length of our lives is determined by how quickly our body is able to carry out running repairs. As the cells miss opportunities to repair themselves, our bodies gradually degrade until we eventually die.

據(jù)英國《每日郵報(bào)》報(bào)道，英國紐卡斯?fàn)柎髮W(xué)的教授湯姆?克伍德最新研究發(fā)現(xiàn)，女人壽命普遍比男人長，這是因?yàn)槟腥说纳眢w在生物學(xué)上更像是“一次性用品”。這一頗具爭(zhēng)議的理論指出，女人的身體比男人更善于進(jìn)行常規(guī)保養(yǎng)，保持細(xì)胞的自我修復(fù)和活力。壽命的長短是由身體出現(xiàn)的細(xì)微錯(cuò)誤的多少?zèng)Q定的；隨著體內(nèi)細(xì)微錯(cuò)誤的累積，人體細(xì)胞的自我修復(fù)能力又決定了我們壽命的長短。因此，那些總是不能及時(shí)進(jìn)行細(xì)胞修復(fù)的人，身體會(huì)逐漸衰老直至死亡。
