Thought the exact same thing.
You will always look younger than your age btw. I’m 50 and I regularly get mistaken for early to mid 30s.
It’s the constant harassment and fatigue of living with many men that ages women. Most people will tell you that it’s kids. But I have one and that’s not it.
You raise your kids to participate in the family unit and act like an actual functioning family where everybody pitches in to complete whatever needs to be done instead of dumping all the labor of running and managing a household on mom and you won’t be so constantly tired and stressed, and harried that you age quickly.
