I know Villagers who lead wonderful social lives without imbibing in alcoholic beverages. One can engage in activities of all sorts without drinking or toking for that matter.
Now all that being said alcoholism among the elderly remains hush-hush and not widely recognized and treated. Some became alcoholics long before they retired; others became so over the years after they stopped working and had plenty of leisure time to drink on their hands. The Villages obviously provides ample opportunities to indulge in alcohol at many venues. Drinks are unbelievably cheap at bars and restaurants in TV and happy hours start earlier than anywhere I have ever lived before. In all fairness my guess is one would find a lot of drinking at any retirement community be it TV, a Sun City or otherwise.
