I remember a guy who retired from the Navy after 20 years.
I asked him how many combined years he spent at sea.
He replied, "seven".
The Navy recruiter said I qualified to go to nuclear powerplant operator school. The thought of being on a nuclear sub for extended periods didn't sound like fun.
On the brighter side:
The Navy is known for having the best food.
Sailors typically achieve higher levels of education during service compared to members of the other services.
The myth that a sailor has a woman in every port is just that.
