In summary, early retirement is a choice. The global economy is making it difficult to achieve it, but we can still try our best to plan toward enjoying it by saving, investing, and healthy living.
Of course we can make ourselves happy in life and even retire early even with the way the world seems to be manipulative, it's our choice to make the earth a heaven for us. all we can do is just to put our time in planning and executing our plans on how we can retire early.
Although this days I haven't seen an elderly person that retired early all I see is people working too hard to make a living yet retirement only meet them and not them retire at will as the economy in some countries has put them in this shoes but we can make ours different.
