Want to raise your IQ? Pump up your heart rate!
In Spark: The Revolutionary New Science of Exercise and the Brain, Dr. John Ratey reveals how exercise can help ward off anxiety, dementia and depression, all while increasing your intelligence.
In Dr. Ratey's blog you'll find a free download of his presentation from the Learning & The Brain Conference. There's a lot of interesting information in there, like the study of rats who ran voluntarily 48 km a day over several weeks.
