I'd like to ask everyone to send good thoughts and prayers to our blogpal Lisa J. Cohen; she and her family are dealing with the aftermath of a house fire. Her husband has pictures posted on Flickr here of the terrible damage it caused. One great blessing is that they were able to get out of the house in time.
Each year during the holiday season fires kill 400+ people, injure 1,650 more, and cause over $990 million in damage.* Houses can be rebuilt and possessions replaced, but fire-related injuries are often devastating, and lives lost to fire are simply gone forever.
So: if you didn't put fresh batteries in your smoke detectors back when the time changed, please do it today. If you don't have smoke detectors in your home, please buy and install some now. Also, make sure you have an escape plan to get out in the event of a fire, and talk to your kids about it.
