Why Are There So Many Divorces With Celebrities?

When it comes to entertainment news outside of movie making, new movie trailer, how is a scene filmed, the next project, etc..... 

Why are there lot of news of celebrities divorcing? Do they not care about later in life. Like say at 68 or at 75. Aa adults gets older there going to be health problem(s). How may people, celebrities or not  going to get very very lucky? He or she not going to have Diabetes, Neuropathy, Cholesterol problem, Stroke, Heart Disease, Any types of Cancer you can think of that out there, Cataracts, Glaucoma, etc..... They going need each other. Even through they got the money to hire good home aid help. But still it more of each other of all those years, that you want one other at that moment not the hire home aid. Going to the doctor right away.

Do they think at 25 or 37, they will be able find someone else. That it not a problem. What about having to live alone outside of work for the time being, think about real everyday people that have to live  alone, with or without a Mental Health problem(s). He or she could be say 37, 43, 47, 55 or 63. Don't they ever think like that. where real everyday people got face those things how ever their life is.

I don't think real every day people even have as much divorces as celebrities. When you look into researches on the subject ands the stats of it.

I think the smart ones are, Gary Sinise & Moira Harris, Tom Hanks & Rita Wilson, Howie Mandel & Terry Mandel, John Travolta & Kelly Preston, etc...
