40 Years Together

The last two days my thoughts have been geared toward the party we Horst children are planning for Vernon's parents' 40th wedding anniversary in March.
I was just now thinking, WOW. I wonder what we'll be like when we've been married that long? How many descendants we'll have, where we'll be living, if Vern will have recognized his dream and be a doctor, etc.

Vernon's parents have 7 children, with all but 2 of those married, and there are 18 grandchildren, presently.

So now for the married folks: (sorry, single friends)
How many years have YOU been married? Do you have any children?
