Nintendo DS

Finally, I got a Nintendo DS which was a popular game console in Japan today. I'm not a gamer and never have game console yet. But I wanted it because the software for adults was sold. I bought the software named "DS brain training for adults" with DS. The software imposes some daily trainings on us. It seems the daily training gets active our brain which ages after 20. We can check our brain age with the software. For your information, my brain age was 30. It was 2 years younger than I really was. I was relieved. But I will train everyday so as not to age.
