As far as I am concerned, I got the job of my choice and I am able to use my skills in my career and I enjoyed fruits out of it. I am very much satisfied with my career and now I am spending relaxed retirement life.
Knowledge is power.
I think retired people who have great skills should use their skills to benefit young generation. They may be proven as guide and teacher to them. Their experience will benefit young strugglers. One of my maternal uncle was a retired professor (Chemistry). After his retirement he returned his home town and renovated his home. He opened his gate to all students. So, students of intermediate, graduation and P.G. would come to him if they found any problem in chemistry.
