The fact that it is easier to find work in a naval setting than in most fields may mislead some into thinking that it is literally a matter of turning up, being given a uniform and calling yourself by your rank, but this is of course not the case. You will need to pass aptitude tests and a physical examination, and even this is dependant upon whether a policy of recruitment is in place at the time. Should these conditions be in place, though, it is an industry with positions on offer in a time when such things are not so common elsewhere.
And this is where the crux of the matter lies. Are you prepared to face a change in your way of life that will at times make emotional demands upon you that are greater than any physical demand the job offers? If so, then there are positions for you, but you should make sure that you do not go into the industry with your eyes shut. If you take a positive attitude with you and take every situation on its merits, the Navy could well be the place for you.
