Since this is under Medical and Health Discussion, I am guessing the observation is from a medical background, with the knowledge that each person observed is retired and living here.

Or could the OPs observation be those who are here for that multi day world win lifestyle, that in a few fleeting days think they need to make the decision of a lifetime.
Or those who have just a few days to get their new house in order to return to their current home.
Or the growing population that have moved here working remotely from home.
Possibly the many who are visiting and trying to capture every moment as quickly as possible.
As for it being a medical issue I would need to leave that up to their health care provider
