I have a friend who had her first child at age 39 and another at 41. She doesn't look old for her age. She is probably 20-30 pounds overweight, but that's neither here nor there as far as it making her look older. On more than one occasion, she's been mistaken for their grandmother. As you might imagine, it really bums her out.
I have to admit to feeling somewhat conscious of my age relative to others, in part, because I'm married to someone much younger than. With him, I don't feel the difference all that much. With his friends, I do for sure. We've had reason to see a big group of them lately. Sometimes, I take comfort in being older and, in some ways, wiser and more experienced. I'm arguably in better shape than many of them, too, physically and financially, which soothes my ego when I've feeling "old." We have no intention of having kids, so that creates a disconnect on some level, especially among my husband's friends' spouses. I'm used to that with my own friends though, too. But my friends with kids are old enough at this point to see the green grass on both sides of that equation. So, we usually don't struggle to find a good middle ground.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
