There is always a demand for talent. I found that if you have done it before, its like riding a bike. And plus there are so many "as you say" young bucks that get the job, however they really cannot perform the task that is only achieved with years of experience. I have worked in the industry for 38 years and I just enjoy training the technicians who need to advance to the next level. There is too much emphasis on job security and Companies need to use the older experienced people to get their house in order to train the upcoming generation. A college degree is just a piece of paper that can get you in the front door. It basically says" you are teachable". Experience is something you develop of years of making mistakes and perfecting the skills. They cannot teach that in college. So, yes you are still valuable. so are so many older Engineers that could teach in plants and give companies a "1" up on global competition.
