Anyway, just to reply to some of the comments: I mentioned the # of kids to present some reasoning behind the biological limitation to get married at 27. But kids and family are still fairly distant in the future for me, so it can change, I recognize that (i.e. haven't totally boxed myself in).
But let's even look at the more interesting side: men who want families have the OPTION of staying single well into their thirties without limiting the number of people who they could statistically find a match from. A 35 year old man has many more potential marriage partners than a 35 year old woman. And I think that is not going to change until it is as common for a 35 year old woman to date and marry a 5+ years younger man as it is for the reverse case.
I should mention that I am super open minded about these things - I am just observing some realities around me, not commenting on whether they are good or bad.
