How rare is that now a days? And, just as a point of reference, I'm not in my 40's.
What I have learned from my parents is that marriage is work. That there are good times and bad, but the good times outweigh the bad and you grow.
That marriage is a commitment. That it is something that should not be taken for granted.
That you never, ever speak ill of your spouse in public - EVER.
That it gets better with time.
That there is give and take and sometimes you get spun around, it's kind of like the hokey-pokey.
