It is very unfortunate if people who have reached the age to retire are forced to work again because to meet their needs, it is necessary to prepare early for retirement. In each country, pensions are applied at different ages for those who are old so they can rest and maintain their health. or also because winning at an old age is no longer productive / maximal at work.
I think it all comes back to yourself, and whether you want to retire at a young or old age depends on a person's readiness to meet their needs. If someone is sure that they have a lot of savings and will meet their needs for a long time then there is no harm in taking a pension anytime.
You are absolutely right that it can be unfortunate that one is forced to work even after retirement.Such a situation is common in countries whose financial position is not stable and their economy is running badly.Even after retirement age, they have to work under compulsion because their financial position is not stable,and the condition of poor countries is even worse where people work till they die.People who have a good monthly income can prepare to meet their needs before retirement, but how can people who have nothing left from their monthly income prepare for their post-retirement needs?
Even in our country, pension is implemented for old people after retirement so that they can spend the rest of their life comfortably, but the pension of the majority is not so much that they can cover their monthly expenses.So they have to work again to meet their expenses.Of course, those who can meet their needs can retire at any time,but it depends on how much savings he has and what is his financial position.
