I've been really working on my Golf game for the last few years. One thing that I've noticed is that I still hit ~about the same number of bad shots as I always have, its just now they're less bad than they used to be.

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.

It’s obvious in retrospect, but wasn’t intuitively clear earlier in life: your primary life partnership is somewhere between medicine and poison. Kate is medicine. Her mind tickles me, touch soothes, and essence animates. No life decision more important than who you journey with

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 😅

Wild how risky startups are perceived and yet… Anyone who isn’t at one is putting their entire career at risk.

@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.

@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.

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

Assume positive intent is one of the worst pieces of advice at work. Telling someone to assume positive intent is the same as saying "just trust me". What should we do instead? Flip this around. Tell people your motives: "Here's why I'm doing this" "Here's the problem we're solving"

any team in the world would be crazy not to spend that $ on a season with a #1 draft pick, regardless of the outcome.

@Austen small but significant anecdote: a half dozen people in Portland stopped me to ask about BYU and AJ. Had never heard or really considered BYU s as anything noteworthy before this season. Tell me the marketing department gets that kind of reach with a $7M budget.

Yes, it was a disappointing season overall. Yes, we did not figure out a team identity that worked well enough to put the team (or AJ) into the Final Four. But it’s hard to argue that you could have achieved more with that $7M being spent elsewhere.

@TrentMano @rachelle_morris @ChickfilA my favorite Chick-fil-a spelling experience came from the staff going from “Sharp” at checkout to “Frank” at milkshake delivery. Sharp >> Shark >> Phark >> Frank

One of the best stories ever.
Dr. Lemma@DoctorLemma

19 years ago, a high school basketball coach put his team manager into a game for the final four minutes. The kid had never played a single minute of competitive basketball in his life. He scored 20 points. Jason McElwain was diagnosed with severe autism at age two. He didn’t speak until he was five. He couldn’t chew solid food until he was six. He wore a nappy for most of his early childhood. As a baby, he was rigid, wouldn’t make eye contact, and hid in corners away from other children. He tried out for his school basketball team every year and got cut every time. Too small. Too slight. Barely 5’6 and about 54 kilograms. But he loved the game so much that his mum called the school and asked if there was any way he could be involved. The coach created a team manager role for him. For three years, McElwain showed up to every practice and every game. He wore a shirt and tie on match days. He ran drills, handed out water, kept stats, and cheered every basket like he’d scored it himself. On 15 February 2006, the last home game of his final school year, the coach let him suit up in a proper jersey and sit on the bench. With four minutes left and a comfortable lead, the coach sent him in. His first shot missed. His second missed. Then something shifted. He hit a three-pointer. Then another. Then another. His teammates stopped shooting entirely and just kept passing him the ball. He hit six three-pointers and a two-pointer. 20 points in four minutes. The highest scorer in the game. When the final buzzer went, the entire crowd rushed the court and lifted him onto their shoulders. His mum tapped the coach on the shoulder, in tears. “This is the nicest gift you could have ever given my son.” McElwain won the ESPY Award for Best Moment in Sports that year, beating out some of the biggest names in professional sport. He’s 36 now. He works at a local supermarket, coaches basketball, has run 17 marathons including five Boston Marathons, and travels the country speaking about never giving up. When asked about that night, his coach still gets emotional. “For him to come in and seize the moment like he did was certainly more than I ever expected. I was an emotional wreck.”
