Health is more important; with good health, you can earn how much ever you want, but you can't buy good health with money.
"Wealth is nothing without health", as health is a necessary requirement in one's life and wealth is a satisfactory condition; we need both of them to be happy. You will have a sense of well-being and feel happy when you're physically fit; it's not necessary that wealth will do the same.
Most people mistakenly think that having money will solve all their problems, health issues and be happy. There is the inevitable fact that some diseases still have no cure; studies have proved that most rich suffer from anxiety, stress, suspicion, and unhappiness, as being wealthy can rob your peace of mind.
