The Need for PM at Home
I flew home from Chicago last night and my flight, as most others, was about 4 hours late (I presume due to wind, as it wasn't snowing). I got home and into bed at 2:30 AM. So, my night's sleep was already ruined.
But, to make it worse, I was done in by not replacing my smoke alarm batteries on a fixed “preventive maintenance” type schedule. The batteries on two smoke alarms, including the one in my bedroom, were “chirping” every 30 seconds or so, the “andon” that the battery needs replacing soon. Being 2:30 AM and all, my wife and I decided to just try to sleep through the chirping. The alternative was turning the lights on and getting a ladder out, not a good plan at 2:30 AM. Not a great nights sleep.
I have myself to blame on the lack of PM. You're supposed to change smoke alarm batteries every six months or every year, depending on who you listen to. My “root cause” fix is to put this on my calendar so Outlook reminds me to change the batteries BEFORE they go dead and the chirping starts during the night. Better to get the ladder out during the daytime and to change a battery earlier than needed. The battery cost isn't that much.
So, I need to practice what I preach: do preventive maintenance in a PLANNED and standardized way. Better to be proactive than waiting for something to “break down.” You might ruin more than a night's sleep (or two night's sleep if it's you and a spouse).
