ran into our old LS circle 5 yrs later... who's still in?

we took a 4 yr break from the LS for a bunch of reasons (kids, job, life). went to an event last weekend on a whim and saw 3 couples from our old circle. one couple still going strong, swung with them back in the day, lovely catch up. one couple divorced and one half is still active solo (didnt see that coming). one couple is here but is now just spectator-vanilla curious. is this typical of a 5 year reunion in the LS? felt like a school reunion but kinkier... half the people had changed completely
