Do you think that it's a "red flag" if a person isn't married by a certain age? (say, age 50?) Why / why not?
Nah, there's nothing maladjusted about just being unmarried. Marriage isn't (or shouldn't be) a duty or requirement for a person or a couple. And if someone does want to get married eventually, they shouldn't feel pressured to do before they reach a certain age. You can get braces when you're 50, and you can also be unmarried. It's OK.
