For human beings, motion is life. Our bodies are made to move. By exercising modestly on a regular basis, we can change the rate of our aging on a biochemical level. Regular exercise also improves mood, boosts energy levels, and builds self-confidence.

Vaguer the task, or more abstract the thinking it requires; the less likely you are to finish it.
The terahertz (1 trillion cycles per second) gap refers to a portion of the electromagnetic spectrum where efficient generation, detection, and manipulation of radiation have been very challenging. It’s found from 0.1 THz to 10 THz, between the technologies of infrared/optics and microwave/electronics.
Passes through clothing, paper, plastics, ceramics. Strongly absorbed by water and many molecules. Sensitive to moisture; good for spectroscopy. Reflects off metals. Safer than X-rays for human scanning.
Wireless Communication (6G and beyond) — THz bands offer enormous bandwidth for ultra-high-speed data (terabits per second), though with short range and high atmospheric absorption.
Humans are amphibians – half spirit and half animal.
As spirits they belong to the eternal world, but as animals they inhabit time.
This means that while their spirit can be directed to an eternal object, their bodies, passions, and imaginations are in continual change, for to be in time means to change.
Their nearest approach to constancy, therefore, is undulation – the repeated return to a level from which they repeatedly fall back, a series of troughs & peaks.
If you watch carefully, you will see this undulation in every department of his life – his interest in his work, his affection for his friends, his physical appetites, all go up & down.
As long as he lives on earth periods of emotional and bodily richness and liveliness will alternate with periods of numbness & poverty.
Fun is closely related to Joy – a sort of emotional froth arising from the play instinct; it promotes charity, courage, contentment, and many other evils.

Change the clock twice a year, or else some places will need to adjust their operating hours.
Going back to permanent Daylight Savings Time has been tried before, and failed after two years.
What is the issue about the light & night that we keep forgetting?
Think of the flow of thoughts in your mind as a social media feed. Throughout your life, you have “subscribed” to different things without noticing. Now their posts keep showing up in your feed, and you don’t know from where. Some are true & interesting, but many are unhelpful or simply untrue.
Practical Meditation by Giovanni Dienstmann
Brother Francis produced the blueprint. “The highwayman was kind enough to leave this in my keeping, Holy Father. He – he mistook it for a copy of the illumination which I was bringing as a gift.”
“You did not correct his mistake?”
Brother Francis blushed. “I’m ashamed to admit, Holy Father –”
“This, then, is the original relic you found in the crypt?”
“Yes –”
The Pope’s smile became wry. “So, then – the bandit thought your work was the treasure itself? Ah – even a robber can have a keen eye for art, yes? Monsignor Aguerra told us of the beauty of your commemoration. What a pity that it was stolen.”
“It was nothing, Holy Father. I only regret that I wasted fifteen years.”
“Wasted? How ‘wasted’? If the robber had not been misled by the beauty of your commemoration, he might have taken this, might he not?”
