My grandma is 88 years old, and grandpa is 90 years old.
They don't retire, so active in their farmer's life still now.
If farmers can do farm, they don't need retirement.
They are living with nature.
Wake up when the sun rise and then going to their farm and rice terrace.
Make rice and vegetables for themselves.
If it rain, they have a tea time with neighborhood daytime.
Self-sufficiency is very natural for human being.
