I fully agree with you about communicating, but I’m not persuaded that translates to movement or is required for wisdom, which I think you’re broadly describing.

Physical movement can be joy. Dancing, running with children, playing sports with friends, and even just taking care of errands like cleaning so we can get on to enjoying our spaces with our friends and family are all benefits from being able to move and react faster. And I imagine any number of things will slow me down as I age, so I’ll take a +10% wherever I can get it!
