Since I was a kid, I always knew that it's better to make love with my wife at home, than being killed mindlessly, or becoming an invalid, while covered in dirty mud.
When hippies started saying make love, not war, it was obvious for me.
I know that people used to join the army because they were willing to protect their country. But right now it's not a secret that the army is not protecting citizens, but is used as a tool for depopulation.
So why married men choose to join the army instead of enjoying life?
esp knowing how likely it is to be cheated while on duty
Why does X do Y? Because:
Reason 1: 0.6
Reason 2: 0.4
Reason 3: 0.2
Reason 4: 0.05
Sounds quite algorithmic, right? Add to that the fact that another factor can be something like daily variance, a mood, a moment of reflection, or even "randomness" to make that choice, which may be an alternate to other options or the status quo.
So why do people go to the military? A sense of patriotism, doing the right thing, the concept of self-sacrifice for the country, honor, money, because their status quo sucks, and because it can provide options for the future (or at least the idea that it could).
