妇女 比男人活得长。人们认为,人的年龄不会比 女性在每个年龄段都更弱。相反,我认为男人 老得更快。从进化的角度来看, 年轻的男性与快速衰老是相容的。机械地,超激活 mTOR(雷帕霉素靶蛋白)可能会使年轻男性健壮,但代价是 加速老化但如果女性衰老较慢,那么为什么是女性 更年期?有些人认为更年期是有计划和有目的的 (祖母理论)相反,我讨论更年期是如何不是 程序化,而是同一程序的无目的延续, 在青春期开始繁殖这一准计划导致 女性生殖系统的过度活跃,这是非常脆弱的, 过度激活老化和更年期的机制进行了讨论。
Women live longer than men. Yet, it is believed that men do not age faster than women but simply are weaker at every age. In contrast, I discuss that men age faster. From evolutionary perspective, high accidental death rate in young males is compatible with fast aging. Mechanistically, hyper-activated mTOR (Target of Rapamycin) may render young males robust at the cost of accelerated aging. But if women age slower, why then is it women who have menopause? Some believe that menopause is programmed and purposeful (grandmother theory). In contrast, I discuss how menopause is not programmed but rather is an aimless continuation of the same program that initially starts reproduction at puberty. This quasi-program causes over-activation of female reproductive system, which is very vulnerable to over-activation. Mechanisms of aging and menopause are discussed.
