Working out made me understand why people want kids

Lately, through exercise, I've started to understand why people want to have children. At a certain age, the world begins to feel stagnant — a fixed, looping cycle — and you gradually lose the sense that you can still change things. And yet, there's this deep human urge to leave a mark. It's almost silly — that itch to carve "I was here" somewhere you've been. Watching a life grow, slowly, with your own involvement — it gives you this confirmation that you're still capable of creating change. Your will becomes visible again.
