According to the Alzheimer Society of Canada, "healthy lifestyle choices will help keep your brain as healthy as possible as you age. And since a healthier brain can withstand illness better, it's important to take action on the things you can control -- lifestyle choices."

The Society has a number of lifestyle choice recommendations that a person can choose to do including challenging oneself, being socialable, and being physically active.
All three of these suggestions can be accomplished by joining the Ajax Texas Hold'em Bowling League!
As such, there is a chance that joining the ATHBL could possibly be good for your health!
