Exercise and the Brain (?)

Science has this interesting news story on exercise and the brain.  Getting definitive scientific evidence on something as basic as the impact of physical exercise on the human brain is rife with uncertainty, nuance and disagreement.  It requires decades of methodical research before any clear consensus emerge could emerge, if ever.  A sample from the story:

“ … new research reveals a more complex picture. One recent review of the literature suggests the studies tying exercise to brain health may have important limitations, including small sample sizes. Other studies suggest there is no one-size-fits-all approach to exercising as a way to boost cognition or prevent age-related cognitive decline. Still others indicate exercise may actually be harmful in people with certain medical conditions.”
