So, the next time Hugh Hefner gets engaged to a 20-something or Buzz Aldrin dates someone 30 years his junior, perhaps we should encourage them; chances are, their marriages won't end in divorce.
And, even if Demi and Ashton don't make it, we shouldn't give up hope on December-May marriages, either; if Hugh Jackman, 42, and his 55-year-old wife, Deborra-Lee Furness, can last for 15 years -- happily, one presumes -- so can the rest of us.
So all of these couples have a pretty good shot of making it for the long haul.
But, then again, they celebrities — so they’ve got that going against them… Celebrity status aside, if any of these couples hit the 10-year mark, they’ll already have more than a 90 percent chance of lasting forever — or, you know, until death do them part.
Plus, the couples felt stigmatized by others, especially the wives -- and those judgments may even impact a woman's mortality.
"Couples with younger husbands violate social norms and thus suffer from social sanctions," says Sven Drefahl of the Max Planck Institute for Demographic Research.
Not to say that they're not happy for a while -- certainly Demi and Ashton have appeared to be, as well as the eight couples in a 2006 study by Sandra L. Proulx in which the wives were a decade or more older than their husbands (an admittedly small sample).
At 64, Macron's wife Brigitte is 24 years older than him.
In fact, it found that any kind of gap puts you at a higher risk for divorce. This is good news for newlyweds Mary-Kate Olsen and Olivier Sarkozy, who have a 16-year gap between them, Demi Lovato and Wilmer Valderrama, who have a 13-year one, Blake Lively and Ryan Reynolds, who have an 11-year gap, and Rosie Huntington-Whitely and fiancé Jason Statham, who have 20 years between them.
A five-year age gap means you’re 18 percent more likely to divorce, and it goes all the way up to 39 percent for a 10-year age difference. Lovato and Valderrama are going on four years together, Lively and Reynolds started dating in 2011 before marrying in 2012, Olsen and Sarkozy dated for two years before marrying in the fall and Whitely and Statham have been dating for six years.
, 20-something Max (Kat Dennings), who’s dating a guy about 10-12 years her senior, tells Caroline (Beth Behrs), who has been set up with a 75-year-old played by silver fox, George Hamilton: “If me and Randy are May-December, you two are May-Dead.” Well, research shows that Max may be right… A 2014 study out of Emory University shows just how important the age gap may be when it comes to the lasting success of a relationship.
The study looked at 3,000 people and found that a larger age gap means a more likely chance of divorce. Even May-April 15 romances may not work, depending on various other factors.
