　　It is the ultimate battle of the sexes - and women usually win.

　　这是两性之间的终极较量——而且通常女性获胜。

　　Now scientists have come up with a new theory for why woman live, on average, longer than men: men are more biologically ‘disposable’.

　　如今，关于女性为何通常比男性长寿，科学家们提出了一种新的说法：从生理上来讲，男性的身体更“不耐用”。

　　The controversial theory, developed by Professor Tom Kirkwood of the University of Newcastle, suggests that the female body is better at carrying out routine maintenance and keeping the body’s cells alive.

　　这一颇具争议的理论是由纽卡斯尔大学的汤姆 柯克伍德教授提出来的。他认为，女性的身体更易于进行日常保养，使身体细胞存活。
