1. Changing Your Smoke Alarm Batteries
Every year when we set our clocks back or forward for Daylight Saving Time, they always tell you to replace your smoke alarm batteries.
When the batteries in my smoke alarm die, my smoke alarm lets me know by making an unbearably annoying noise. Usually starting at like 2AM.
I’m not arguing that smoke alarms aren’t important. (Quite the contrary. I’m a big fan.) I’m just saying that it seems dumb and wasteful to change your smoke alarm batteries before it’s time.
2. Tooth Brushing Time
The standard advice has always been to “brush your teeth for two minutes.” I get that.
But now that I have a Sonicare, I find that it too wants you to brush your teeth for two minutes.
The two-minute recommendation is, I assume, a function of the number of brush strokes the average person can deploy by hand. And not a function of the actual clock time your mouth spends being brushed.
With the Sonicare, I’m using about a billion more brush strokes per minute than I could when I brushed by hand. So why am I still supposed to stand there, supersonic toothbrush ringing my head like a bell, for a full two minutes?
(On an unrelated note, I ended up having to get a tetanus shot this morning. I wanted to mention it here so that the next time I wonder “How long has it been since I had a tetanus shot?” I can just search the blog to find out. How do non-bloggers ever manage, I wonder?)
