Many of the quirks of the elderly are caused by small-farmer thinking,

They hardly eat protein, afraid that eating too many eggs will harm their health, and to buy free-range eggs, they have to go through connections,
After all the fuss, their total intake is basically zero,
Meat prices have risen to five yuan per jin, frying a pound of meat is faster and cheaper than cooking a plate of vegetables,
They only pursue rice, steamed buns, and pickled vegetables every day, emaciated and suffering from diabetes and hypertension,
They believe that eating meat is harmful, hard to digest, and causes weight gain,
Insist on hand-washing clothes, thinking their own limited skills can compare to industrial machines like washing machines,
As long as they feel clean inside, they believe they are clean,
Reject tumble dryers, reject dishwashers,
Debating daily about the countless benefits of the sun, and the hundred efficient ways to wash dishes by hand,
They only work hard without thinking, torturing themselves from five in the morning to ten at night,
Finally convincing themselves that effort alone can lead to success, never studying methodology, productivity, or scientific development.
