An awesome way to pass the time on the train to work!

Hi, When you are sitting on a long and monotonous train journey and you are bored of your phone and your tablet how about giving your old grey matter a workout. This game, that I sometimes play, I find gives my brain a bit of a workout. Basically think of a date or a year and try and think what happened on that date or year in history. It's amazing what you can remember. A definite mind work out!
