Prolonging life,,, How many money do people pay for it? Now, people in developed country, depends on each country’s medical care. Can we sell it for other rich people who lives in developing country? This means that social medical care is not only for each country’s people, but for foreigners. And this will be big business for saving medical care costs. If we can sell our medical care for foreigners, we can save fixed cost. And it will save huge debts by governments. And not only medical care, but health care will be big business. For example, “Stop smoking”, “Stop being fat” and “Stop drinking”… These program of training will be good for health, clearly.
