WHY do people get fat with age?

As people age, their metabolism (proteins, fats and carbohydrates) slows down. And even with the same lifestyle as in your youth, it will be harder to stay in tip-top shape in adulthood.

Also, as time passes, people tend to achieve a higher social status, which requires less physical activity.
