🥩 What are we supposed to eat:
I think it's important to understand both sides of an argument, so I frequently try and understand plant-based diet rationale. I was listening to a plant-based diet advocate this week, and his argument was that since fruits and vegetables pass through the digestive system quickly it's evidence that we should be eating mostly / only plant-based foods.
I truly cannot understand this perspective. These foods pass through the alimentary canal quickly because they can't be absorbed or used. It is waste. However, as you may have experienced, if you only eat meat there's not a lot of waste. It's absorbed extremely efficiently.
While I'd argue the extreme efficiency that meat is absorbed in the small intestines is evidence for a meat-based diet, it's just one piece of an overwhelming amount, such as:
- Humans have among the most acidic stomachs in the animal kingdom comparable to carrion feeders and common to carnivorous animals.(r)
- We have largely lost our ability to ferment fibers into SCFAs as our cecum is mostly a useless vestigial appendage.
- We share similar, well-developed gallbladders comparable to that of wolves and lions.
- We have vertical up-and-down chewing jaws rather than the side-to-side, rotary mechanism of herbivores that graze all day.
- The human brain is over 7X bigger and uses 30X more energy than would be predicted for an animal our size...meaning meat allowed humans to escape the energetic constraint that limits the number of cortical neurons that can be afforded by a raw plant-based diet in the wild. (r)
Most omnivorous animals specialize in eating animals or plants (~70%+ of one or the other), and the evidence is overwhelming that humans are omnivores specialized for eating meat (could even be classified as facultative carnivores). ( r)
But what about our teeth?!
They look like "herbivore teeth" so we must be plant-based eaters, right?
Humans are primates and our evolutionary biology is derived from this heritage. Therefore we have teeth similar to other apes in terms of size, shape and number. Yet we have developed more ridged molars like wolves instead of flat ones like sheep. Yes, we do have small canine teeth and relatively smaller jaws. But this is because humans
started using tools millions of years ago and fire hundreds of thousands of years ago to kill, cut, and cook the meat. Less mastication forces were needed. Additionally, since canines were predominately defense and intimidation mechanisms, the smaller canine represents a shift in social structure and mating behavior that results from cooperation, communication, and a reduction in male-to-male conflict.
For similar reasons, we have nails instead of claws – because we are primates. Primates don’t have claws. In no way does this suggest we are designed for a plant-based diet.

💤 What music will put you to sleep:
After Dr. Keith Sigel had a kid (and subsequent loss of sleep) he turned his research efforts to discovering how he could get more shut-eye.
Sifting through massive amounts of data, he found that humans feel most peaceful when in an environment that emulates the womb: a warm, dark environment with a rhythmic heart beat, steady breathing, and the slow churn of a body deep at rest.
Luckily, Sigel is a musician, so he began to shape this data into sound, which gave birth to Slowave, a musical landscape (Spotify playlist) to re-create this peaceful environment sonically, and put your right to sleep.
Don't listen while driving.

🔟 How to find the right words:
Finding the right words to explain your ideas and creations is almost as important as the idea/creation itself. These words are the bridge to the discovery of your work. Here's how to find language-market fit.
- Uncover struggles and hidden assumptions
- Discover the "job-to-done"
- Clarify the end goal
Don't get fancy. Use clear, functional messaging so people understand. "Just Do it" comes after you just do it.

🏌️ What series I have teed up:
Two of my favorite bitcoiners, Preston Pysh and Robert Breedlove, recorded a 6 episode series exploring two books that have nothing to do with bitcoin:
- The Brain by David Eagleman
- The Seat of the Soul by Gary Zukav.
I wanted to share this for 2 reasons:
- I'm genuinely looking forward to tuning in
- I admire when people "step out of their lane" for which they are known, especially if it's not popular with their audience.

🧠 What to do:
"To me, the answer is to do what excites you. Do what you feel compelled to do. Do it for the work itself, irrespective of outcome.
The work is the reward."

⁉️ What the FUD:
There's a lot of FUD (Fear Uncertainty and Doubt) in the markets. Is the FED going to tighten? Inflation (up to 6.8%)? Deflation? Evergrande? Debt ceiling?
While I'm not sure about the outcomes of the current market FUD (I can speculate that the FED can't really tighten due to historic debt load and low interest rates, the debt ceiling will be raised, and currency debasement seems a foregone conclusion, while deflationary forces should continue their trajectory with tech and demographics), but if you have any bitcoin FUD, here's your answers.

🏃♀️ How to know your kid's future is bright:
If they are doing this with Legos. Impossible not to watch to the end after getting started.
