Just as you thought: these ladies have posed in various stages of deshabille for a calendar, and it's all kind of sweet, like that elderly musical group that performs "I Wanna Be Sedated". Oh, there's always an element of advantage-taking in these things, and mild loss of dignity, but older people don't have any dignity in our society anyway, so I say go for it. These ladies have not retired to the deck chairs yet, they're in the pool splashing with the rest of us. I just hope they're not incontinent.
