Note: As Mike Yassa, the lead author on the study, pointed out to me, the study did not actually test whether consuming caffeine before a task enhances memory, the problem being that other confounding factors can then lead to difference in performances on the test.
The US debt is more than $20.1 trillion, the largest in the world. Here are the 3 reasons it grew so large, and how it damages U.S. economic growth. The US debt is more than $20.1 trillion, the largest in the world.
Total Debt. The average American has a total debt of $36,714.69. For a family of two it would be $73,429.38. Mortgage Debt. The average American has mortgage debt of $26,434.58 ($52,869.15 per family). This is a good example of the problems that occur when dividing by the total population and using averages is tricky. Approximately 68% of people in America own homes (or have titles to homes that they pay mortgages on).
