I want to get into gardening, but “to boost brain health” seems like a weird way of medicalizing it, of needing to justify it

Why not do it because it seems fun and interesting?

Doesn’t doing anything boost brain health? Like exercising, playing an instrument, volunteering, etc

gardening is different, as there is a persistant, but unproven, suggestion that bieng in contact with soil and plants, changes your personal biome in a benificial way

everything's like that lately, we always need to be optimizing.

Yup, anything does boost brain health, except possibly excess screen time, and in that note, I'll sign off now ;-)

Getting outside is great
