A week ago I went for the first time since 9/11 to a funeral again for a firefighter. Nine years after 9/11 people still die from the impact of the attack and collapse of the WTC. Since 2001 more than a thousand first responders have died from cancer and lung diseases related to toxic dust on Ground Zero. This came as a shock to me, I knew people were sick and some died, but not on this large scale. The death of William Quick, 55, of Long Island is a reminder of the struggle taking place mostly out of sight.
