Poker is my brain exercise. I have to be on my toes, calulating odds and percentages for each hand I play.

I have to read faces for "tells" and remember every hand played at the table, who played it and how they played it previously.

I have to remember who is a tight player, who is loose, passive agressive, a rock or a donkey.

Then I look down at my two cards and decide how I will play before the flop, after the flop, on the turn and on the river..

Raise, reraise, check raise, check, bet or bluff?
...or fold.
Every week, I keep a journal of people I play with and how they play...

It keeps me very active and brain alert.

I firmly believe that using our brain replaces old cells with new ones.

I have the brain of a 20 year old....
Not good, is it?
