As a graybeard with teenage kids, this is terribly disheartening... I would rather be cannon fodder than my sons. After all, I have already reproduced and I have taught hundreds of youngsters all what I knew. I would gladly accept that my contribution to mankind is already done and gone, before seeing one of my children go to war. Is youth so important for soldiers? Wouldn't it be better to send forty and fifty year olds to the front? Anything before 18-26 youngs? It makes no sense. Are they so much more competent than any random middle-age?
