Most retired people nowadays already have a job for another 3 - 4 years ..I guess people would rather keep doing the same thing all through their life rather than try to make most of their productive years ..I know of one couple both just retired since they are of the same age,  who are travelling. Thy have planned everything meticulously down to daily budget and are driving , taking turns, all through the country and beyond to Burma, Thailand , Vietnam etc.. There is no point in working all through your life without making the most of it ..

Even after my retirement from Public Sector Steel plant, I prefer working and being active

It is best to travel to different places after retirement. If you can write, it will be appropriate to write your service time antecedents. If you wish to do some full time job, it will be better to do something that your service experience justifies. For example, an employee retired from Taxation/ revenue can beging tax consultancy. 

I prefer to write . No do not like to do a job. I prefer to be active

Traveling is the most enjoyable activity even otherwise , keeps you fit and makes you aware and broad-minded. I make it a point to save and travel during vacation s to nearby places since there is so much to see within our state and outside too..after retirement one can travel whenever possible ..

Now I am doing a bit of social service. I am educating my maid servant's daughter

Enjoying remaining life is best to do after retirement.

Keep away from interfering in other lives.

In our society, its the retired and other elderly people who normally have busy schedule. They are generally expected to attend the social ceremonies related to marriage, birth, death and other life events. In fact many of these ceremonies remain incomplete without them. 

That is what I have been doing ever since I retired. A retired person should not think that there is no life after retirement
