Hmm. I see what you're saying with that last one (statistical sample), but the number of people who are going to get married (and divorced) is still going to be enormous enough that the veracity of studies won't be particularly impacted.
I already quoted what I disagreed with re: sex, not really any point to miss.
Quote:As to the amount of sex (for examlpe), if they are "ill, disabled or just not in the mood" the relationship will suffer and hence will be less successful (all other things staying the same).
By using "they" you indicate that both people are experiencing this. That was also how Jes used it when it first came up. Yet you say that the relationship WILL suffer. Why, if it is by mutual preference?
Take four people, A, B, C, and D. A and B prefer to have sex 5 X a day. C and D prefer to have sex once a week.
If A and B get married, they have sex 5 X a day, and they're happy. That's a successful marriage.
If C and D get married, they have sex once a week, and they're happy. That's a successful marriage.
If A and C or B and D get married, they won't have sex as often as A/B wants OR they'll have sex way more than C/D wants. That's an unsuccessful marriage.
The way you phrased it, it sounds like you think C and D have a less successful marriage than A and B. I disagree.
