Different languages, similar encoding efficiency: Comparable information rates across the human communicative niche | Science Advances
In terms of encoded data, humans generally operate at 39.15 bits/sec regardless of language. Which means that languages that have low information per syllable must speak faster to compensate. Japanese seems to encode at 5 bits/syllable so must talk fast. On the other end, it looks like US english is capped at 9 syllables/sec so audio processing into information (mental objects) is a possible limiter on the high end.

Why are conversations limited to about four people? A theoretical exploration of the conversation size constraint - ScienceDirect
Which might suggest freeform conversations in meetings only really work well at 4 or less people, or else you have the ritual/social equivalent of a conch token to control speakers (which effectively cuts speaker count to compensate). The take that you are effectively tracking potentially 8 "endpoints" also suggests some connection with memory limits (you generally can handle 7 things simultaneously, maybe don't count yourself?)

Through the Google Glass: The impact of heads-up displays on visual attention | ...
An interesting takeaway is the thesis that HUD notifications compete for language processing time in the visual cortex due to unconscious tendency to process language. This might imply text notifications are worse than iconography, but what about situations where single word characters exist like in japanese/chinese? Is that language processing, or iconography pattern matching?

Smartphone attached patch thingy you stick on your head, which can stimulate alertfulness without outright shocking you or drugging you up. Might be decent, but uses disposable contact strips you need to replace.

Domestic cats
Cats have two basic types of purring. One is the solicitation purr, which actually has a frequency spike around 470-480Hz. The solicitation purr is made often when the cat wants food or something (those with cats who sit on their face trying to wake you up in the morning will understand). It turns out the frequency spike is apparently quite similar to a human baby crying. So the cat is an evil manipulative bastard that tries to reuse human instinct to respond to baby needs for itself. The other purring is apparently just generic, but there was past research that the 50-60Hz regular purring is actually a cat bone resonant frequency, that causes bone segments on either side of a microfracture to periodically come in contact, eventually "sticking" and helping to heal the microfracture much faster than just plain cellular repair. Anyone with cats should remember episodes where the cat has injured itself and is then suddenly purring.
