How Many Sleep How Much?

Here are percentages of who sleeps how much. Actual percentages can vary by country, lifestyle, and individual circumstances.

1 hour: ~0% (usually due to severe sleep disorders or extreme circumstances) 2 hours: ~0.5% or less (very rare and usually due to sleep disorders or extreme conditions) 3 hours: ~1% (rare, often linked to insomnia, shift work, or other disruptions) 4 hours: ~1%–3% (a very small percentage, often due to chronic sleep deprivation or lifestyle demands) 5 hours: ~5%–7% (some adults function on this amount, but it’s below the recommended range) 6 hours: ~30%–40% (common but still considered short sleep for most adults) 7 hours: ~25%–30% (meets the minimum recommendation for adults) 8 hours: ~25%–30% (the ideal amount for many adults, within the recommended range) 9 hours: ~5%–10% (acceptable for some adults but on the higher end of the recommendation) 10+ hours: ~2%-4%

Most people fall within the 6-8 hour range, with 7–8 hours being the most commonly reported and considered optimal for health.

UNCERTAINTY IS CERTAIN

Uncertainty is Certain G. Donald Allen 12/12/2024 1. Introduction . This short essay is about uncertainty in people from both secular and nonsecular viewpoints. One point that will emerge is that randomly based uncertainty can be a driver for religious structure. Many groups facing uncertainty about their future are deeply religious or rely on faith as a source of comfort, resilience, and guidance. The intersection of uncertainty and religiosity often stems from the human need to find meaning, hope, and stability in the face of unpredictable or challenging circumstances. We first take up the connections of uncertainty to religion for the first real profession, farming, noting that hunting has many similar uncertainties. Below are groups that commonly lean on religious beliefs amidst uncertainty. This short essay is a follow-up to a previous piece on certainty (https://used-ideas.blogspot.com/2024/12/certainty-is-also-emotion.html). U...

Where is AI (Artificial Intelligence) Going?

How to view Artificial Intelligence (AI). Imagine you go to the store to buy a TV, but all they have are 1950s models, black and white, circular screens, picture rolls, and picture imperfect, no remote. You’d say no thanks. Back in the day, they sold wildly. The TV was a must-have for everyone with $250 to spend* (about $3000 today). Compared to where AI is today, this is more or less where TVs were 70 years ago. In only a few decades AI will be advanced beyond comprehension, just like TVs today are from the 50s viewpoint. Just like we could not imagine where the video concept was going back then, we cannot really imagine where AI is going. Buckle up. But it will be spectacular. *Back then minimum wage was $0.75/hr. Thus, a TV cost more than eight weeks' wages. -------------------------

Principles of Insufficiency and Sufficiency

The principles we use but don't know it. 1. Introduction . Every field, scientific or otherwise, rests on foundational principles—think buoyancy, behavior, or democracy. Here, we explore a unique subset: principles modified by "insufficiency" and "sufficiency." While you may never have heard of them, you use them often. These terms frame principles that blend theory, practicality, and aspiration, by offering distinct perspectives. Insufficiency often implies inaction unless justified, while sufficiency suggests something exists or must be done. We’ll examine key examples and introduce a new principle with potential significance. As a principle of principles of these is that something or some action is not done enough while others may be done too much. The first six (§2-6) of our principles are in the literature, and you can easily search them online. The others are relatively new, but fit the concepts in the real world. At times, these pri...
