Dr. Mark Tarnopolsky stated that "if there were a drug that could do for human health everything that exercise can, it would likely be the most valuable pharmaceutical ever developed." But before we explain why, let's ask a different question. Why do you think you have a brain? Neuroscientist Daniel Wolpert explains in his TedTalk that the physiological purpose of our brains' existence is to facilitate movement.
During his talk, Mr. Wolpert explains that the looking throughout the animal kingdom, we can see a direct correlation between complexity of movement and complexity of the brain powering that creature, even when considering evolutionary pathways for that particular animal (meaning that if an animal used to move more 1000 years ago, their brains were larger than they are now).
If brains are required for movement, then wouldn't that mean movement is good for our brains? Absolutely! The You Tube channel What I've Learned, has an excellent video that will explain it all. This is the most valuable 15 minutes of your day today, so please pay attention. Here are a couple of the key facts from this video:
Kids who exercised vigorously could remember vocabulary works 20x faster than kids who did not.
Exercise 30 minutes per day, 3 days a week has been proven just as effective as Zoloft in treating depression.
