Thanks, DJ.
I had an uncle who worked for IBM, was at the Merrill Lynch building at World Trade Center (green-dome building if you're looking at pictures of the area) on 9/11. He was outside when the first tower came down, and joined the throngs of people that ran out of Manhattan.
Unfortunately, though he never drank or smoked his entire life, he developed some sort of auto-immune disease and lung spots that affected his breathing around 2005, and died painfully in 2010. At his funeral, one of his closest friends told me that thousands more people were suffering similarly...believed to be caused by breathing that terrible dust for several hours on that day. I've heard it many times since then: 3,000 people died on 9/11, possibly 10,000 more New Yorkers in the following years from exposure to the WTC wreckage.
I say this because the events of 9/11 affected us all directly, and indirectly. Never forget...
