Sept. 11 is a day filled with tragedy, sadness and remembrance, but it is transforming into a day of service, too.
Houston Mayor Annise Parker showed her support Tuesday and encouraged others by speaking to more than 100 city employees about the importance of CPR.
"Every day, thousands of people start off on an ordinary day and don't make it home because they have a heart attack," Parker said.
She can directly relate to the cause as her own father died of a heart attack. He was a marathoner and very fit, but a heart attack was just too much for him.
"He had been having heart pains. I knew that, but he didn't seek treatment," Parker said.
Parker hopes that by training some city employees, they'll be prepared if someone needs live-saving help.
The goal is for the trainees to become trainers and educate five friends or family members on basic CPR.
