It's not in the article ... it's common knowledge his wife is a few years older than him, I pulled the 4 from memory.
I didn't know that Mrs. Tomassi was older than he is. Since he's 55, that would mean she's pushing 60. I never thought she was substantially younger but I would have guessed she was something like 1-3 years younger.
After 16 years of marriage I can honestly say there are no appreciable advantages (outside of raising children) that a man cannot enjoy single that he can married.
That might be true in theory, but it might not be true in practice. In practice, it's a bit more complicated and it really depends.
The biggest problem is that a lot of men are pussie beggars. A lot of unattached, unmarried men struggle to get laid on a consistent basis. Most unmarried men will need at least an unmarried relationship in order to get laid consistently.
Married men don't have to make the effort to seduce new pussie, which can be a time savings. In the modern marriage, there is not a lot of sex after the first few years of marriage. Men married 5+ years are often getting more sex than an incel or borderline incel, and a lot of unattached men are incel or borderline incel. A guy in an unmarried relationship with a decent sex life is going to get more sex than most married men.
A married man might get more social invitations after his early to mid 30s as compared to a completely unattached man. Social circles tend to dry up for unattached men in their 30s/40s, even with more and more Millennials being childless. Unmarried, attached men have slightly better social lives because they can do some couples activities. For 30s/40s people today, the default is still married couples and they typically have children.
A lot of the newer, Millennial wives are not amazing home cooks unlike previous generations of women. The typical Millennial married man can't assume he'll get better home cooked meals as a married man than he would as an unmarried man living separately from a girlfriend or being attached.
