Singapore: What's Life?

While Chinese are celebrating Chinese New Year, I was asking, "What's Life? Why do people work hard all their lives and then, even with all the preventions, contract illnesses and return all the money they've earned to the doctor?"
A woman even had to sell her house, (Choy! Choy! Choy!) which she has worked hard to buy, to pay the doctor! She has always been health-concious, exercised regularly, eat carefully, rest adequately, relates well with people, and did many good deeds.
So why??? Are people on a big merry-go-round?
