So I figured I'd check my battery to see if it said Sony and, while I was at it, get the serial number for later. So I pull my laptop and power cable out of my carrying bag; by plugging the laptop in, I think you can remove the battery without the computer losing power.
I get the laptop upside down on my desk and get a coin for the little battery locking mechanism. Twist that, pop the battery out, record the serial number printed in little squint-inducing gray type.
Those of you with working memories have already deduced what comes next. I look down and, coiled idly on the floor below my desk, is my power cord.
I really worry about what I'll be like at retirement age. Life will be a voyage of constant discovery.
