    I wonder if there will be total information transparency in the future. Society has run on morals and ethics but we're transitioning to an era that will increase the importance of thermodynamics.

    We demand that AI show its reasoning so that we can see what's happening inside

    Heavy social media users visibly decline 1-2 points in attractiveness i.e. 7 to a 5.

    This is a real, quantifiable biological effect from the health tax created by social media. I saw the 10% tax in my biomarkers from a 40 hr fast (consistent with broader evidence).

    @alpaysh I do see a drop in my RHR when cuddling with Kate before bed. Her presence and touch calms my nervous system.

    My heart rate before bed last night: 38 bpm

    In the 99.9th percentile.

    The 40 hour social media fast dropped it by around 10%. Seems social media could be a 10% tax on my nervous system.

    The best way to overcome fatigue and a lack of self confidence is to build life control systems. Master these this week:

    + in bed some time every night
    + final meal 4 hrs before bed

    + exercise every single day, even if a little
