Why does it feel that the time passes faster as we get older? What is the physical basis for the impression that some days are slower than others? Why do we tend to focus on the unusual (the surprise), not on the ever present? This article unveils the physics basis for these common observations. The reason is that the measurable ‘clock time’ is not the same as the time perceived by the human mind. The ‘mind time’ is a sequence of images, i.e. reflections of nature that are fed by stimuli from sensory organs. The rate at which changes in mental images are perceived decreases with age, because of several physical features that change with age: saccades frequency, body size, pathways degradation, etc. The misalignment between mental-image time and clock time serves to unite the voluminous observations of this phenomenon in the literature with the constructal law of evolution of flow architecture, as physics… More here.

An excellent publication.

First, when we accumulate a sleep debt, we lose some of the subjective ability to judge how that lack of sleep affects us.
Second, even though we don’t realize it, objective tests show that we continue to have “deficits … in vigilance and episodic memory” even after “2-3 nights of recovery sleep.” Key: The deficits persist even if we feel “less tired” after recovery sleep.
Finally, and perhaps most alarmingly, studies suggest that this persistent sleep loss — even when we try to catch up on it — can lead to “heightened susceptibility to neurodegenerative disorders, including Alzheimer’s disease … and Parkinson’s disease (PD).” More here.

The problem is that it is SO difficult to control. A healthier diet, drinking less coffee, more exercise, sleep tracking and so many other ideas I have tried. And not one of them has made any difference to me- for so long I have averaged between 5 and 6 hours a night, and I suspect I am stuck with that forever more.

If there’s one myth that has persisted through the years without much evidence, it’s this: multiply your dog’s age by seven to calculate how old they are in “human years.” In other words, the old adage says, a four-year-old dog is similar in physiological age to a 28-year-old person.

But a new study by researchers at University of California San Diego School of Medicine throws that out the window. Instead, they created a formula that more accurately compares the ages of humans and dogs. The formula is based on the changing patterns of methyl groups in dog and human genomes — how many of these chemical tags and where they’re located — as they age. Since the two species don’t age at the same rate over their lifespans, it turns out it’s not a perfectly linear comparison, as the 1:7 years rule-of-thumb would suggest… More here.

Ignoring the fact that we do not need to know what our dog’s age is in comparison to human years, it is reassuring to know that the way they age is not linear. Nice to know that Murray was 60 (human) years old when he died.

Daily cases: 67,159 (up by 23,142 from last week)

Hospitalisations: 11,639 (up by 827 from last week)

Deaths: 123 (up by 49 from last week)

The original source is here (scroll down a bit). The fact that there has been nothing happening in the UK that would cause such increases across the board is concerning.

I can only presume that it is waining immunity from the boosters, but even with Ukraine and so many other things happening we really should not take our eye off the ball here. The numbers, especially the hospitalisations and deaths, should not be going up.
