Yeah, this is something that people don't talk about enough. Doing puzzles, healthy eating, exercise, and other factors are important too but, social support and social interactions have also been shown in multiple studies to reduce the risk of developing dementia.

Of course, it's all correlations so we don't know what directly causes what, but given that even the best medications for dementia are not very effective, we need to come at this with all weapons we got.

From the abstract:

"Here, we show that the circadian clock controls the timing of late-stage floret development, or anthesis, in domesticated sunflowers. In these plants, up to thousands of individual florets are tightly packed onto a capitulum disk. While early floret development occurs continuously across capitula to generate iconic spiral phyllotaxy, during anthesis floret development occurs in discrete ring-like pseudowhorls with up to hundreds of florets undergoing simultaneous maturation. "

That's so interesting.
