Nadhani ni kwa sababu uzee una negative connotations in the West. Westerners wanaposikia "uzee" wanafikiria wrinkles (ugliness), boringness, old-fashioned, whereas youth is exciting, new, interesting, beautiful. The female gender is supposed to be pretty and attractive, and old-age is considered as anything but this, so i think this makes women more reluctant to accept that they're aging (even though men tend to have some problems with it too once they're over 30 from what i've seen). And being that the Western culture is very influencial and thus tends to affect non-western cultures too, i think this mentality is unfortunally increasingly spreading among non-westerners too.
