So I went out to buy a Nintendo DS Lite along with the game Brain Age. So far it has been a great addition to my daily routine. I do a sudoku in the morning, my usual one from google ig, and when I come home from work I do the daily training from Brain Age and sometimes an additional sudoku from the game as well. I like it much better than the random things I was doing before to keep my brain active and it seems to be much more effective. I no longer feel as sluggish most days.
Plus the other games I have for the NDS are awesome fun as well. Good job Nintendo.
