I really enjoyed the Art Kramer Talk. It basically emphasized the point that we've all heard countless times from our parents and elders: that exercise is good for you. Kramer showed how much it's good for you, and how exercise affects the brain directly. One aspect that really caught my attention was his demonstration of how exercise affects the ability to multitask. It's interesting how children who are fit are also able to do multitasking better than those children who did very little exercise. He proved this with the video of the treadmill experiment where a fit child is able to cross the road while talking on the cell phone, but if a less fit child does the same, it would not work. The most interesting part of the talk was the part about Olga Kotelko, who woman over 90 years who is still a Canadian track athlete. At such an age she can actively run and compete in races. Her exercise increases neurotransmitters in the brain and allows greater neuronal connections, which in turn causes her activeness in sports. Exercising allows the brain to shrink less as you age.
