Exercising your brain is just as important as exercising your body. The Brain Fitness Challenge lets you test your mental agility and raise money for neuroscience.
Sign up a team of friends or coworkers for the event and you'll compete in a series of online challenges which begin on November 17 and continue for a week. Prizes are being awarded for the best results, as well as the teams who raise the most funds, which go to Florey Neuroscience Institutes. Hit the site for full details and to register.
