If you don't buy a house or a car to raise children, having so much money doesn't really serve much purpose. When you get seriously ill, you'll wait to die; minor illnesses don't cost much, and there's health insurance for moderate illnesses.

Eating too much can make you sick; eat less for health. As for clothes, many can be worn for over ten years without wearing out. If you're not tired of them, there's no need to buy new ones.
Why is everyone fleeing now, resisting buying a house, a car, getting married, or having children? It's simply because they don't want to make themselves too tired or fall into a trap.
