Sad news yesterday, as Jeff Bezos and MacKenzie Bezos, who have been married for 25 years and have four kids, announced on Twitter that they're getting divorced. 

Sometimes it's for the best. I know from firsthand experience, and I'll bet many readers do, too: Couples can get divorced, and they can often go on to find better relationships with other people.

They can also often remain on civil terms with one another, or even stay friends remain family, as the Bezoses say they expect to do. 

In fact a common refrain among replies to the Jeff and MacKenzie's Twitter announcement was that their divorce sounded more caring and thoughtful than a lot of people's marriages.

Still, it's always a difficult thing to go through. You can only imagine how complicated and expensive an untangling it will be between the world's wealthiest person and the woman who has been with him since before he started Amazon.

Far more than money or professional accomplishment, most studies suggest that personal relationships are the key to happiness. It's hard to imagine a more crucial relationship than the one you have with your spouse.

Once you get beyond the scale of their assets, however, the Bezos's situation doesn't seem all that unusual among entrepreneurs. While hard numbers are hard to find, a statistician named Nathan Yau pulled data from the U.S. Census Bureau in 2017, and correlated professions with likelihood of divorce.  

"Entrepreneur" and "business leader" aren't considered job categories with the census, apparently. But, the data on the jobs that are listed suggests a pattern: the higher stress and higher risk your profession is, the less likely you'll stay married.

S​ound at all like your job? The big caveat is that people who made more money were less likely to get divorced, which obviously suggests the Bezos situation isn't quite typical.

Still, it's worth thinking about: If you're happily married, and you're a business owner, what can you do to ensure that you remain both of those things at the same time?
