The Return of Dr Kawashima

I wouldn't mind betting some of you had a Nintendo DS Lite just for the brain training program. This probably dates back to 2007/2008 about the time that I retired. I found it in a drawer in a sideboard that I haven't looked in for a long while.

It's not unusual to find bits of old tech in cupboards or drawers in our house but what was unusual was to slide the switch on the side and find it came to life! I was amazed, it must have been there untouched at least 12 years. Those Nintendos must have had excellent rechargeable batteries.

It told me that my brain age was 42 back when I was using it. Hmm? I wonder if it's anywhere near that now?
