Should I Continue to Care?

I'm turning 40 this year and I'm finding it hard to keep up with fashion trends and pop culture. Just 5 or 6 years ago, I was super fashionable and in the know. Now I feel dated. I did have two kids over the last 5 years but I look at myself and think, "what happened? ".

Those over 40, do you care to keep up with fashion and pop culture? Is it even worth it anymore?

I don't want to look dated. I remember seeing women who looked dated when I was younger and I felt bad for them....
