Perspective as US Debt approaches $20 trillion

From Market Watch: The U.S. national debt is closing in on $20 trillion. That’s $20-thousand billion. Or $20-million million. If you stacked up $20-trillion worth of thousand-dollar bills, it would supposedly reach something like 1,200 miles high. If you lived to be 80 years old, you’d have to spend about $700 million a day to run out of money.
