Do people that are married for many years still "make out," in other words, french kiss for an extended period of time?

at work yesterday we got into a discussion of whether or not married people that have been married for 20, 30, 40 years still make out. it seems like the general consensus is that they do not. for those that don’t know, the term “make out” means french kissing for an extended period of time, maybe also known as “necking.”
