@djsmith42 @RaminNasibov that’s it

[Cahlan Sharp @cahlan]

@djsmith42 @RaminNasibov even on Steam? I guess it’s been a bit since I’ve played the first one

[Cahlan Sharp @cahlan]

@djsmith42 @RaminNasibov I just played Portal 2 through again on Fri night. Those are such great games.

Want to learn about unconditional love? Have babies.

Want to learn about love that provides safety and security while watching miraculous growth? Raise toddlers.

Want to learn about how to balance love-as-safety and love-as-accountability? Raise teenagers.

Parenting is a masterclass in all types of love.

[Cahlan Sharp @cahlan]

If you ever want to learn about ruinous empathy, have teenagers.

While not all CEOs are great, the good ones do their job: align the company behind a direction, doggedly pursue the future while pragmatically execute the “now,” and make hard calls. This is one of the few things humans are uniquely capable of doing well.

This is like saying the only thing holding back the potential of the river are the banks that direct it.

[Barrett @SledgeDev]

CEO's are the bottle neck to productivity. I am launching a CEO model this will eliminate this bottle neck, reduce costs and increase developer productivity 100x. Human CEO's going to need to get some real skills and learn to actually work, cause they are going away in 6 months

@BrysonWebster @AndyDelecto this is the way.

@BrysonWebster @logannichol My guess is that we’ll shorten them often to Builders/Messengers/Gatherers which I think works a lot better than an age group

@BrysonWebster @logannichol “11–13 year old class” def doesn’t roll off the tongue

"I came back to change that."

A student reporter who is graduating in May told Gerry McNamara he never saw Syracuse play an NCAA tournament game. His response is exactly what Cuse fans want to hear 🍊🔥

@Ryan_Holdaway It’s crazy too because what you consider “bad” also changes

@BrysonWebster I couldn’t even finish it 🤷‍♂️

Your romantic partner is the single highest-dose pharmacological input in your daily environment. Bryan Johnson frames this as poetry. The data is more violent than that.

The Harvard Study of Adult Development tracked people for over 80 years. Relationship quality at age 50 predicted physical health at age 80 better than cholesterol, income, or career success. The mechanism is a specific neuroendocrine cascade. A supportive partner triggers oxytocin release, which suppresses cortisol, downregulates HPA axis activation, reduces systemic inflammation, and slows telomere attrition. Your cells literally divide longer before hitting senescence. The person sleeping next to you is either extending or compressing your biological clock at the chromosomal level, every single night.

Now run the numbers on the poison side. Married adults in one sample had a telomere T/S ratio of 1.70. Unmarried adults: 1.58. That gap held after controlling for diet, exercise, smoking, obesity, and social support. Divorced men in a Swedish cohort showed 46% higher relative mortality risk. A separate study of 3,526 adults found marital disruption was associated with shorter telomere length even after adjusting for neuroticism and lifetime traumatic events. The inflammatory profile of a high-conflict marriage looks nearly identical to the biomarker signature of chronic work stress or long-term caregiving burden.

This is the part people miss. Bryan said “somewhere between medicine and poison.” The pharmacology is more binary than that. Oxytocin from a quality partnership lowers blood pressure, reduces sympathetic nervous system activation, and improves immune surveillance. Chronic cortisol from a bad one drives the same oxidative damage to telomere cap structures that accelerates every major age-related disease. There is no neutral. The dose is always running.

A 2003 study found that more frequent partner hugs correlated directly with lower resting blood pressure and heart rate. The cardiovascular system responds to your primary attachment bond the way a tissue responds to a drug. Dose, frequency, duration.

“Medicine and poison” is the right frame. But Bryan undersold the dosage. This is the single largest uncontrolled variable in every longevity protocol on Earth, and almost nobody is tracking it.

Now is the 'good ole days'. These are the golden years. Any year spent with most of your health, with loved ones close by, and doing something you can tolerate is a great year.

@gentryld @_renatov Maybe another way of saying this is “creating a startup puts some amount of the risk of your livelihood within your control.”

I used to tell people that the only job security you really have is the job you create for yourself. True, but that creation is painfully difficult 😅

[Cahlan Sharp @cahlan]

@CriddleBenjamin and yet, how many people remembered (or even heard of) those squads? Having a #1 draft pick is worth the price, regardless of how disappointing the outcome was.

[Cahlan Sharp @cahlan]

@djsmith42 Maybe there’s a conflation of intent and motive. Maybe they’re the same thing? English is hard.

It just seems like there’s a space you can give someone, even when you disagree vehemently, that respects that they’re doing the best they can with what they have.

[Cahlan Sharp @cahlan]

@djsmith42 Maybe it would be better said “assume positive motive?”
