Of course, it sounds absurd to suggest that a man's wife would kick one to the curb because his physical peak has passed, so how does it make any sense to imagine that a husband would be inclined to get rid of his wife simply because she isn't 22 anymore? Because there are more attractive women out there? There always were. There may be a few more than there were before, but he always had other options. Is a woman going to eventually be eclipsed by twenty-somethings? Of course, it is the way of the world.
Read it all. Later in the post:
it is so tragic when women, particularly women over thirty, cast aside their husbands in search of something better. Because no matter whom they meet, no one will ever look at them again through love goggles, which like beer goggles, tend to make a man see a woman through a soft and flattering lens as her mythical and eternally youthful self rather than the harsh, objective light of reality.
Looks do matter but they're not the only thing. As long as a woman doesn't turn into a whale after marriage and isn't disrespectful to her husband (both of which are not mutally exclusive), then she shouldn't worry much.
