This year’s Nobel Prize in Physics made me wonder the role of Einstein’s physical activity when he calculated the existence of gravitational waves some 100 years ago. We might not remember him best as the ambassador of exercise and physical activity, but based on biographies written about him it is evident that in addition to spending lots of time thinking and discussing with his friends, he also liked to walk around and spend time┬áup on the┬ámountains. Maybe he had realized that there really is something there with the muscle and mind connection, as shown recently by the Swedish researchers. Maybe Einstein would have made his calculations and other ideas even without being physically active, but as we currently know that physical activity can boost your memory, creativity and productivity, it is quite likely that Einstein’s walking trips also contributed to his amazing intelligence.
