@femalelongevity So exciting! Congrats! Really keen to learn from your experience. Thank you for sharing this with the world.

Job hunting is oddly similar to the dating experience of men..

THEM:
- “So you don’t have any experience? No thanks. I want someone with experience and leadership qualities. That’s attractive.”
- “You’ve done a lot of job hopping. Why’s that? Seems unreliable.”
- “You’ve stayed in the same company for 10 years. That’s lame and I feel like you’re too attached to them now.”
- “You need to try harder. I expect you to pursue me. Write a cover letter.”
- “Ew, you come across as desperate. No.”

YOU: Actually, I found a job last week, so it’s all good.

THEM: You have? Where at? You seem like a really good fit. Are you sure you want to stay there? Our salary is highly competitive. I think you deserve better.

(After 100+ applications) Suddenly, you become the most attractive candidate in the market.

@bryan_johnson Night terrors happened to me many times in the past. They suck. They were correlated with heavy stress and anxiety. I had plenty of sleep deprivation in the past too, but they gave me irritability not night terrors.

Three years ago, David had any seemingly-healthy person’s worst nightmare: his TruDiagnostic results showed a biological age that was 4.7 years older than his chronological age. Oh no.

Generally, this type of result backfires. The person complains about the company and argues their exceptional health: “Clearly, I am not that unhealthy, as I can run 10km.” They accuse the company of producing fear-mongering reports that are unhelpful to the population. They make a philosophical stance: “I refuse to become some health-obsessed person, living in anxiety. What is the point of life if I can’t live properly, anyway?”

David didn’t do any of that. He simply said, “hmm.. I wonder why.” Because David didn’t feel anxious. He felt curiosity. And a touch of excitement.

Most progress starts at that point. It starts from one’s curiosity, open-mindedness and desire to change.

This year, David’s biological age was 6 years younger than his chronological age. That’s a 10.7-year swing in three years.

I provided an overview as to how David systematically and gradually changed his lifestyle to pull his biological age younger in my latest article. I believe this will be helpful to a lot of fellas who are confused as to where to begin.

@cooljessedude @KingVelesI Good tip. Actually curious.

Majority of the people already work in jobs that don't require novel use of their brains. If AI partially replaces people's jobs, then they will still use their brains, but for other tasks. If AI fully replaces people's jobs, then a more important question is how are we gonna pay for a "brain gym". I'm sure we'll still have access to books, chess, instruments, sudoku, and a ton of other ways to use our brains. There are some companies focused on building a "brain gym" though, also assessing "brain health." They look interesting.

[Doa Fitzgerald @DoaFitzgerald]

Some people just can't be bothered doing the repetitive "boring" stuff every day. Some people also struggle with delayed gratification. They expect to get in shape in a week, learn a language in three months, etc.
Though when someone asks me "did you turned it off and on again," I make a protesting sound because it makes me feel stupid. How did I dive into solving a complex problem without even thinking of doing the most simple thing?! Frustration with myself. 😆

[Doa Fitzgerald @DoaFitzgerald]

@seanheilweil Looks like a great band actually 😆

[Doa Fitzgerald @DoaFitzgerald]

Don't like blanket statements in either way. We can pick and choose what is good for us from nature and from a lab/factory.
Don't think that's what people mean when they say they want natural food though. Just because glasses are good doesn't mean ultra-processed foods are good. There is a need for antibiotics - people can die without them. People don't die if they don't eat artificially produced plant-meat with a list of preservatives and anti-caking agents. And food science made big claims then took a step back, going 'ooops' in the past. Mistakes happen! Unless there is a desperate need, most people don't enjoy experimenting with their bodies. It's a trust problem. The "natural" things are normally foods that have been eaten for +500 years, so it feels safe. We don't go foraging for exotic mushrooms in the forest anymore, so that is no longer our worry.
When our habitat changed from the forest to the city, our dangers have also changed. Now, we're more likely to notice the dangers in our city life than the dangers in nature.

[Doa Fitzgerald @DoaFitzgerald]

@simonmaechling 100% natural = a marketing term ultra-processed food companies love.
I've seen 100% natural oreos before.

[Doa Fitzgerald @DoaFitzgerald]

There are different types of "sugar". We can't compare apple to freshly squeezed orange juice to homemade cake to lollies.
Some things are unhealthy. That's just the truth. But this doesn't mean there has to be a food war happening every week at home. We can believe that some sugars are toxic while making exceptions (and having them). It's good to talk about unhealthy foods while not turning everything dramatic.
Kids need glucose from healthy foods, not processed foods or refined sugars. Those are purely desire, not need.
Repressing desires generally don't end well. At the same time, kids are used to the diet they grow up in. My neighbour's kids didn't grow up eating any ultra-processed foods. I gave her a chocolate bar when she was 9 for the first time, and her face looked up she ate lemon.

[Doa Fitzgerald @DoaFitzgerald]

@Hybridathlete Both are necessary. Both have their benefits. We need balance in life. It's important to put in the effort to keep in touch with friends. At the same time, nothing can replace family. And kids deepen life's meaning, makes you wanna be a better person.

I experimented with magnesium. Didn't do anything, but got withdrawal symptoms that freaked me out. Rebounded in 2 weeks though. People I know who love magnesium for sleep have their magnesium levels on the lower end of the "healthy" range (blood test). So.. think the answer is solving the root cause problem.

[Doa Fitzgerald @DoaFitzgerald]

You're right, I get it but..
1. Some people own dogs and cats. Are they supposed to clean each paw? A bit torturous for the animal and if you have a cat, good luck attempting that.
2. Kids literally roll on the ground. Some cultures carry their kids like a porcelain doll, but others just let them free.
3. Sometimes outside is muddy, sometimes outside is not super dirty. And some people pick and choose when to walk in with their shoes. Decision of the eye.
4. Some people walk barefoot outside too. Aussies.
5. People just do what their parents do and not think so deeply about the little habits they have.

The Western society only began wearing shoes in their homes during the 20th century. Before the mid-1800s, city streets were unpaved, muddy and had horse 💩. Furniture also became raised, so people had less contact with the floor. Then came the widespread use of vacuum cleaners. All in combination changed the culture.

This study got me thinking and digging for more info.

Why is it that first born children are smarter?

Kristensen & Bjerkedal (2007, Science) ran an experiment on ~250,000 Norwegian male conscripts. They looked at men who were biologically second or third born, but whose older sibling(s) had died in infancy, so they were raised as the eldest.

The result: those men scored like firstborns, not like second-borns.

I guess the advantage is not biological.

[Nicholas Fabiano, MD @NTFabiano]

First born children often have a higher IQ than their siblings.

The Mediterranean diet is a marketing term defended by two types of people:

1. Non-Mediterranians

Just travel to a Mediterranean country, it’ll help you to understand. Most of us cannot live without cheese, yoghurt, lamb, pork. It’s engrained in our identity.

2. People who don’t want to admit their alcohol addition

Just say that you don’t know how to socialise without drinking alcohol. You don’t need to brand it with a health term.

[Doa Fitzgerald @DoaFitzgerald]

Saw a man in his 80s in the gym warming up for 30 minutes, doing balance exercises, etc. Then he walked over to the squat rack and lifted 2x the weight that I squat.

I wanted to fall on my knees and bow to him. Goals. I have not been this impressed in a while.

[Doa Fitzgerald @DoaFitzgerald]

Found a new way to regulate my nervous system.
Hug a calf. Highly recommend.

[Doa Fitzgerald @DoaFitzgerald]

1. Enough for what? Staying alive? You can do that with 5 hours too.
2. Alcohol is poison. "Not any more harmful" makes it sound like you think not drinking alcohol is already harmful. Without a need to find scientific evidence, I believe drinking water is not harmful. On the contrary, it might even be healthy.
3. Impossible to compare. Cardio, strength, muscle mass are all useful for different things.
