useful questions

1. What would you do if success was guaranteed?

I'd be a writer or maybe a scientist.

2. What would you do if you had unlimited money and no obligations?

Probably most of the same things I do now. I'd live a simple, peaceful life. I'd read, write, walk, swim, make AI art, tinker, travel, date, and spend time with family and friends. 

The only big difference is that I'd buy a plot of land and put a mobile home on it. 

3. What would you do if you were immortal and had eternal youth?

I'd go to Mars to help build a settlement there. Maybe every few decades, I'd head back to earth for a vacation. 


Speaking of space colonization, it's a terrible idea for many reasons. The money and effort would be better used making sure civilization survives on earth for thousands of years to come. 99% of species go extinct within 15 million years.

blue zones, longevity, and diversity

The so-called blue zones are locations where most people live long with good health. 

***
The Blue Zones are regions in the world where people live significantly longer and healthier lives. The five official Blue Zones are:

Okinawa, Japan: Known for its high number of centenarians and a diet rich in vegetables and tofu.
Sardinia, Italy: Features a strong community and a diet high in whole grains and healthy fats.
Nicoya Peninsula, Costa Rica: Residents have a strong sense of purpose and a diet rich in beans and corn.
Ikaria, Greece: Known for its Mediterranean diet and active lifestyle, leading to low rates of dementia.
Loma Linda, California, USA: Home to a community of Seventh-day Adventists who follow a plant-based diet and prioritize health 
***

A factor overlooked is that all these places are extremely homogenous. Being around people who are similarly to you lowers stress and fosters strong relationships. 

Vegetables, seafood, swimming, moderate climate, exercise, no tobacco, moderate alcohol - yes, these are all important. Community and a sense of identity is also important. 


***
After scanning the entire United States, the researchers found that Manassas Park, Virginia, a city of roughly 17,000 located 30 miles southwest of Washington, D.C., and Weld County, Colorado, a metropolitan area just north of Denver that’s home to 378,000 people, ranked highest with life expectancies of 96-years-old.

Black folks in those communities are living well past the national average of 74-years-old.

The same can be said for Loudoun, Fairfax, Prince William, and Montgomery counties in Virginia — all located outside of Washington, D.C. — where Black residents are living up to 82-years-old, on average.

Coined as “Chocolate City,” D.C. has historically had a large Black population — making up 45% of the district’s population as of 2021.

“If there is a Wakanda in the United States, it’s the DMV,” or the District of Columbia-Maryland-Virginia corridor, Perry says.

“You have places in Maryland and Virginia, in particular, where Black people are thriving. They’re walking around with Air Jordans. They got the nice, fancy job. They own the homes. They’re living the life, and they’re living longer,” he says.

The DC metro area is about twice black as the US average (24% vs 12%).

The Simpsons vs nuclear power

It's a great show I immensely enjoyed as a kid. I do hate their anti-nuclear propaganda. Earth to morons, flower power will not solve America's energy problems. Also, France gets 70% of its energy from nuclear plants, and they haven't started glowing in the dark.



In real life, there are far more deaths from coal mining and coal power plants than nuclear energy.

Not convinced? Galen Winsor, a former nuclear weapons engineer, ate uranium on camera to prove it's not nearly as dangerous as Hollywood or the government would have us believe:

You probably have a smoke detector in your house. Guess what? It has radioactive material in it.


Fun fact: radiation is probably beneficial in low doses because of hormesis. And food poisoning would barely exist if our food was irradiated.

how much does it cost to build an atomic bomb (U-235) from scratch?

The minimum critical mass is 15 kg. 


Using the above as a shortcut, 1 g of 93% enriched uranium costs $6,690. 

(15,000 g)*$6,690 = $100,350,000

The other costs of building the bomb are negligible in comparison. From this I can conclude that any country that can scrape together a few hundred million dollars can make a nuclear weapon.

There are about 87 countries which spend at least $1 billion per year on their military. Thus, many countries could afford nuclear weapons but choose not to build them. This estimate checks out because Pakistan's annual military is about $7.6 billion and they are a nuclear power. North Korea is also a nuclear power, and they spend about $4,7 billion per year on their military.
