For those of you who have read our articles Watch Your Back…at Work and Watch Your Back…at Home and have wondered if we’d draw from that well again, wonder no longer. Welcome to the third installment of our “Watch Your Back” series! (We’d certainly hate to close the door on any potential Watch Your Back…in Space or Watch Your Back…in the AI Uprising posts.) SportsIf you’re the kind of person who enjoys running, jumping, and/or propelling some sort of ball toward another human being, good for you! Swimming can condition muscles used to support your back, and it can also serve as cross-training for your primary sport.
