I don't believe women past their 20s are "too late in life" to be seeking a partner.
I for one would not want to have a long-term partner with someone below their 20's. They're too young, cannot even go for a casual heart-to-heart over beers/wine, and have no understanding of budgeting, tax analysis, healthcare planning, or any other number of basic adult administration. I'll have to parent them though this, which is supremely un-sexy.
