Eight years ago, at our first ultrasound, my wife (35) got labeled “advanced maternal age.” I was 40. I joked, “If she’s 35 and ‘geriatric,’ what does that make me?” The tech smiled: “You’re an old dad.” I laughed—and Old Daddin’ was born. If women are labeled “geriatric” at 35+, then dads are Old Dads at around 35+. Own it.
