For the past month and a half or so I’ve been aiming to lose weight. I got to the point where my fat pants were starting to get tight and I was not about to get another size bigger.

I also have a scale that I’ve been getting on every day to dutifully report my slowly shrinking weight.

I noticed an alert on my phone that the scale’s battery was starting to get low. I figured I have a whole mess of mostly full batteries that I pulled out of the smoke detectors (which is why I didn’t throw those batteries out) so without thinking I swapped out the four AA cells and got back on the scale.

I’m guessing there is some voltage-dependent non-linearity. The scale immediately read three pounds lighter.

:-)

Sometimes surprises can be rather nice.
