As a veteran, I used to encourage younger people who were still confused about what to do with their lives (that’s before they started staring at cellphones during every hour they were awake) to go into the military for a few years. I don’t do that anymore.
I know what you mean, I don’t think I would be comfortable in a sub with some of these younger guys, knowing how we had to depend on eachother when the crap hit the fan!
