#2TL;DR
"muscle fitness (measured by leg power)" is correlated with cognitive ageing.

#3Walking helps me think because my thighs pump my brain full of smart juice?

Time to do squats!

#5Interesting, however i'd lean towards muscle mass in general having this effect rather than thighs in particular.
Although being at the lower end of the body might be important in maintaining goid circulation.

#6Just started to read the book "Brain Rules: 12 Principles for Surviving and Thriving at Work, Home, and School".
It basically starts with this "For starters, we are not used to sitting at a desk for eight hours a day. From an evolutionary perspective, our brains developed while working out, walking as many as 12 miles a day. The brain still craves that experience, especially in sedentary populations like our own. That’s why exercise boosts brain power (Brain Rule #1) in such populations. Exercisers outperform couch potatoes in long-term memory, reasoning, attention, and problem-solving tasks. I am convinced that integrating exercise into our eight hours at work or school would only be normal."

#7I'd be interested to know more precisely whether the subjects were doing more aerobic or anaerobic exercises.
My hunch, given my distant past life as an athlete, is that the correlation is with aerobic exercise and not anaerobic.

inversely correlated I hope?

Certain types of physical exercise have been shown to markedly (threefold) increase BDNF synthesis in the human brain, a phenomenon which is partly responsible for exercise-induced neurogenesis and improvements in cognitive function
https://en.wikipedia.org/wiki/Neurobiological_effects_of_phy...
People who regularly participate in aerobic exercise have greater scores on neuropsychological function and performance tests. Examples of aerobic exercise that produce these changes are running, jogging, brisk walking, swimming, and cycling. Exercise intensity and duration are positively correlated with the release of neurotrophic factors and the magnitude of nearly all forms of exercise-induced behavioral and neural plasticity; consequently, more pronounced improvements in measures of neuropsychological performance are observed in endurance athletes as compared with recreational athletes or sedentary individuals. Aerobic exercise is also a potent long-term antidepressant and a short-term euphoriant; consequently, consistent exercise has also been shown to produce general improvements in mood and self-esteem in all individuals.

#10The study controls for genetics and upbringing. So somewhere among food, fitness, and the entire rest of the world is a contributor to brain health. How helpful is that?
