There's definitely some churn at that stage, from retirement, divorce, career change, etc. But it brings folks in, at about the same rate it takes them out. My neighborhood group I described above is mostly that demographic, some younger, some older. When the kids leave for college or work, the adults look for other adults to play with. It's a fun stage of life. This group likes outdoorsy things, hiking, canoeing, camping, skiing, along with the usual potlucks and barbecues. Despite the occasional drama, it's mostly been a blast. Human nature's much the same everywhere - the core dynamics don't change in older vs younger groups. At least in my observation.
