Biggest pile of rubbish I have read in a while. It isn't even humorous to read about out of shape and weak people pontificating about how lean athletes are liabilities, will die off first, must for through epiphanies to survive, etc etc.
First things first. It takes more to be able to kill someone that is healthy, muscular, and strong. Second, anyone that is used to disciplining their body through diet and exercise is an asset in times of danger and stress. Two of my friends were army ranger snipers, one had an Iraq combat weight of 242 lbs, the other weighed 225. If you look at your average special operator they carry more weight and muscle than an average soldier. You fools think that you can carry a 100lb ruck very far and you have no strength or muscle...well you are wrong. For most of recorded history"might made right". Those that were big and strong found themselves in charge... And that is still the way for alot of the world.
But keep living in your uneducated world where strength, size, discipline, fitness, and sacrifice mean nothing.
