  • My own personal brain drain

    Now that I’ve completed my first full week back at work, I can confirm the suspicion I raised in my New Year’s post marking my return to blogging that the freedom and energy to write and blog that I discovered over the Christmas vacation have been severely reduced:

    Alongside the where … it’s pertinent to ask, when would I write? Maybe blogging is principally something for the holidays, when I’m rested and have time to reflect and to write.
    On the plus side, I am writing about it here!

    The brain drain

    Why is work - the non-physical work that I do- so draining? What am I doing all day that consumes so much energy, despite mostly sitting about, typing and clicking?

    I’m involved in product development and launches, in technical support, in documentation and report writing, with many context and application switches throughout the day. The energy that I burn in these activities can’t be all that much by themselves. It’s the brain itself, I feel, that becomes tired and lethargic - motivation and discipline come in waves, and I do need to drift for a while - to daydream, or make a coffee, or (in the home office scenario) empty the dishwasher.

    Mental tiredness is something that is analysed in depth in Daniel Kahneman’s Thinking Fast and Slow: that the amygdala running our instincts is the low-energy, high-intensity backup to the frontal lobes that take on most of our controlled, “slow” thought. When the mental energy balance is off kilter, decisions can be made faster, because instinct takes over - but they can be made worse, because of confirmation bias, of assumptions and hopes that the decision was good enough to survive.

    I go for walks, or sometimes for a run during the course of a day, which does help to refresh things - but, at the end of the day, when the work is done and the children are in bed, I find it difficult to decide to engage in another bout of active thinking.

    Audio strain

    At the beginning of the first pandemic lockdown and home-office phase, I hadn’t really given too much consideration to my office setup: I had my decent keyboard, mouse and screen at home, but I quickly found that the laptop audio was killing my ears, and contributing to this energy drain.

    I went through a sequence of trials with various headphones and found that, for longer web conferences, relatively loose-fitting, wired earbud type headphones were better than my professional over-ear ones, as I could hear myself less, the rest of the house could “seep in”, and yet I still had decent sound across the audio bandwidth (those tinny laptop speakers are a killer).

    Slow overthinking, slow overdoing

    Admittedly, I’m not the most energetic of workers or writers, or musicians, or fathers, or engineers, or communicators, or researchers, or sportspeople - I’m a mixed-mode “pulser” rather than a constant turbine. I think I’m pretty good at recognising when I need to “dash” or to relax, but stress does build up over time, as does exhaustion: I can have trouble switching off and sleeping, which is cumulative. Before the Christmas break, I recognised my own warning signs of work-life-induced exhaustion: tiredness with an inability to sleep, an unsettled digestive system and occasional lethargy and headaches. That has all receded, thankfully, but the next accumulation has already begun

    Naturally, we’re back at the start of the work-vacation cycle, so things aren’t too bad: but the combination of this product launch, the Covid pandemic and everything else does mean that blogging here and over at engiphy.net has already slowed down.

    At least it means you don’t have to read too much!

  • Energy considerations

    My stance on energy is an open one: I am for a mix of available technologies.


    • Oil will remain a key component of transportation energy for years to come
    • Coal should be wound down (very slowly)
    • Gas and shale gas are interesting agents for energy balancing
    • Nuclear should be the key base energy driver
    • Renewables should be part of the mix but should nor cannot become dominant sources
    • Local energy (on houses or in communities) are interesting distractions from the energy requirements of whole countries
    • Efficiency drives are necessary (and result in fascinating technological challenges in themselves) but should not return us to the dark ages
    I will come back to each of these as I develop my own knowledge base. My key sources of information are the now classic Sustainable Energy Without the Hot Air by Prof David MacKay and Prof Barry Brook's Brave New Climate blog, which was a key resource for me in becalming the media panic that surrounded the Fukushima Dai-ichi crisis.
