jonsen··on Optimal hydration may slow down the aging process in humans
Generally it depends on if and how fast molecules of water and solvents are able to pass through the membrane.

Say sodium and water passes equally well, there will be a net flow of water one way, and a net flow of sodium the other way. Notice that the flow of water will make the water rise on the flow-to side, then pressure there will rise and oppose the flow.

jonsen··on Ask HN: Concepts that clicked only years after you first encountered them?

jonsen··on Investigation on the effect of oral breathing on cognitive activity (2021)
I did a similar process about two years ago. Started after reading Breath by James Nestor. The book doesn't prescribe anything but gives a very wide perspective of possibilities. I think what really did it for me was breath holding exercises.

jonsen··on Questions about the hard limits of human intelligence
Don't forget memory. Intelligent processes are also a rather involved development of the state of the agents memory.

Take for example Conway's Game of Life. Initial state is "perceived" from the seeder. From there it's a perception-less process.

They say Einstein ruminated ten years on relativity. Did he need much perception for his absolutely not useless result?

You can't hold it indefinitely. Eventually you will have to pass it on. When the process settles you will just induce a delay.
jonsen··on A New Test for an Old Theory About Dreams
The recall of a dream may be realistic, but that does not imply that the actual dream was realistic. If the actual dream is not realistic, if could be possible, that the conscious recall process is realistifying it more or less.

jonsen··on Unconscious bias in media interviews with female top managers
"As communications experts, we can make an important contribution to an equally authentic and individual representation of women and men in their leadership positions by uncovering biases and creating awareness."
