With the change to daylight savings time a while back came the reminder: Did you change the batteries in your smoke and carbon monoxide detectors? Consider this a second reminder for those (like me, for example) who blew right past the first. The life you save might be your own.
And if saving a life isn’t enough to motivate you to do the deed, consider this: It’s a statistically-proven fact that if you let the battery in your smoke/CO detector die on its own it’ll inevitably die at 3-f@$$#ing-30 in the morning and wake you up with its infernal beeping. You’ll find yourself standing in the middle of the house trying to a) stay awake while b) carefully listening for that damn beep every 60 seconds to tell which one died.
