Does middle age REALLY start at 35?

If that’s true, then the have nine more YEARS? I don’t want to be middle age!
People keep saying 35 is when middle age or mid life crisis start. I thought it was 40.
My cousin keeps saying she isn’t middle age and she’s young. She’s pregnant with her first child. Our cousin said, “Wow you wait until you’re middle age to have your first child. You’re a middle age women that’s pregnant. Should of had them young.” She tries to act like she’s 21. Is she middle age? Her husband is 41. She’s 35.
