Wanted: The most boring and most secure job you can find

Hey, I work in a field where I'm "already 29". It's killing my soul.<br><br>I don't know what I can do that requires MINIMAL training or experience, but has a strong job security. I'm not talking coal mining either. I'd love to do something that's mindless and helps me in the long run. I need this desperately.<br><br>What is this job and how do I get into it?<br><br>I'm in the United States.<br><br>&#x200B;
