If you are a programmer and are stuck on a problem, go running and get a clear head to solve the problem in the program code. Nerds can also be great marathon runners or even sprinters. Jogging is the perfect compensation for sitting in front of a computer. Programming and coding is your cardio. After your race you will solve your problem in the algorithm much faster.
