I do agree with Manju Kumar. Let me add here that so long person is active, age is not hurdle and one can even match with the speed of work the young people currenty doing. The advantage of keeping / retaining senior person is that he will concentrate on the job and will not look for leaving the job frequently which is normally leads to train the new person. Here stability, sincerety, dedication and honesty is more important which, of course, senior persons have.
