Surviving the Apocalypse: Protect your back
I know this will sound stupid to many of you, but as a person who has suffered due to a back injury for most of my adult life, I will tell you there is very little as incapacitating as a back injury. When SHTF many of the labor saving devices that we have come to depend on will be a thing of the past, lifting, pulling and carrying heavy loads will be a daily requirement for your survival. DO NOT forget to take care of your back. Learn proper lifting techniques, work on increasing your core strength, and begin now. In a worst case scenario it will save your life, in a best case scenario it will save you some unwanted pain.
