I think we will never be satisfied with money we earned and will keep on earning till we are able to do it. Moreover, nowadays there are many opportunities for officially retired people. Online assignments are also open for all. But it's not only money because some people find it hard to sit idle. It's in their blood to keep on doing something which is really good. It would keep us engaged and mentally refreshed. So I think there should not be any retirement and we should keep on doing something or other. I know some retired Government employees who started writing poems and novels after retirement. It's gives them a happy feeling and also a hope for bright future.
