Similar to "Dr. Kawashima's Brain Training" you can play games to improve your skills. It measures your 'BPI' and compares you to other members. (My name's one80two - add me as a friend!)
My brain profile at the moment (it changes a lot):
Overall - 73% (="you're better than 73% of the other users")
Speed - 68%
Memory - 90%
Attention - 60%
Flexibility - 70%
Problem Solving - 76%
