Based on what I can recollect over the past 21 years I've been married. It is scientific? Probably not.
Starting with my wife, she has no interest in:
Live sporting events
Outdoor activities such as snorkeling, camping, spending time in nature
Hunting/fishing for our food then cooking and eating them
Getting a little wet from the rain without her going into a panic about how were are going to get sick because of a few drops
Real "extreme" activities such as as skydiving. Twice when I was younger, I was invited by my coworkers to take part in their weekend skydiving group. Twice, the wife was vehemently against it to the point she would have made my life a living hell if I disobeyed her.

Expand the above to include her friends who were almost always Filipinas and like-minded. We became members of the local Fil-Am groups at places we lived at. Same story. All the activities are pretty mundane. We can't even get them to do river-boating:
If it's just me, forget it. If several of us hubbies went out as a group, we're allowed. But, none of the wives would come with us. They'd spend their time doing pot lucks while we were gone.

We spent six years in Upstate New York which is an outdoors paradise. Did we take advantage of it? Nope. I'm more than game. But, the wife always played the part of spoiler. Unfortunately, she's setting a bad precedent for the kids who are becoming more like her. They rather go to the mall than spend time camping and enjoying the outdoors.
