Well, with me, I really wouldn't like to have a job, at my age, which is "north of 65". I am now, semi-retired, collecting Social Security benefits here in the U.S. and I have a couple of small pensions from companies that I once worked for. I have been working since I was 18 and still in high school. (I started in the work world in the usual way that JWs start---working for a fellow JW who had a janitorial business. And, I have "moved on" to other work/employment situations since then. I didn't continue as a "janitorial engineer.")
But, a thought went through my mind, back in late 1998, while I was still very much in the work force. At that time, when I was 44 years old, I was working as a Document Control Clerk, at an organization that was managing the design of the toll roads that have been built in this part of Southern California. It was a fairly responsible job, which included extensive data entry, and filing of documents into their proper file cabinets. It also involved distributing copies of the documents to engineers who were on the staff of the company. But, yeah, in late 1998, one day, after doing a lot of data entry concerning recent documents, that had to be added to the database, I sat at my desk, and while looking at the stack of documents, this thought went through my mind...You know, I do believe that I have accomplished EVERYTHING that I really want and/or need, to accomplish in my work life. I really had. I had accomplished everything that I wanted to or needed to accomplish in the work world.
Now, that thought came to my mind, while I was still in the work force. It didn't come about as a result of being laid off, and between jobs. It came to me while I was still working, gainfully employed at an organization. And, it didn't come about because I no longer enjoyed the job, or the people that I was working with. I did enjoy the work and I did enjoy my compatriots...my co-workers, my colleagues. But, I knew, in 1998, that my working years had come to an end, mentally and psychologically. Now, I knew that I would have to continue in the work force. I was 44 years old and not of retirement age, here in the U.S. But, if I had to continue in the work force, it would be against every fiber of my core being. And, of course, I have been employed in various situations since that day in 1998.
However, if someone, anyone, had approached me in 1998 and in the years after that, and offered me $3000.00 per month, to leave the work force, so as to allow someone from the younger generation to come in and take my place, I would have jumped at the chance. I really would have. No questions asked, no regrets.
Now then, getting back to the question posed in the O.P. what kind of job would I like to have, if I ever have to get back into the workforce? Probably doing "voice-overs" for radio and TV commercials. I have been an Amateur Radio operator since November of 1986, and over the years of conversing with fellow Hams, a few of them have told me that they think my voice would lend itself to being "on the radio" or doing voice-overs for commercials. I don't know if that will ever happen. But, perhaps.....Best Regards...Titch.
