A thread on the snippets (paragraphs & quotes) from the book ‘Lifespan’ by David Sinclair @davidasinclair

‘The clock is ticking’

This thread will be updated as I read further & further. Image
1/ “Every death is violent.” ~ Holocaust documentary filmmaker Claude Lanzmann. Image
2/ That scene from the film ‘Dead Poets Society’ Image
3/ And Nothing was ever the same again.

The author is talking about 50 extra years of Health-span being the norm. Image
4/ 400crore years ago, we started with a 2 genes in a single cell with this mechanism👇 to survive, now we are at 21000 genes & 30Trillion cells. Image
5/ We are the great survivors. Image
6/ Car T-cell therapy explained: Expected to grow at 45%+ for the next 7 years 🚀 Image
7/ Consuming products filled with antioxidants does no good. It’s a marketing gimmick. Image
8/ How the scientists will push back death. Image
9/ There are 2 types of information in our cells: Digital (Genome) & Analog (Epigenome) ImageImage
Simpler explanation for Epigentics: explains how nuture (not nature) leads to changes in your DNA.

Simply, how 2 twins which have the same genes can have diametrically opposite lives.
10/ Why people who exercise or fast seem younger: Hormesis. Image
11/ That’s what is humbling about nature: something like yeast that is used in brewing beer can also help cure cancer. Image
12/ Why Yeast? 😉 Image
13/ epigenome’s design. ImageImage
14/ Simplest explanation of the epigenome: its melodious. Image
15/ A caterpillar can’t transform to a human, but only into a butterfly: Why the genome is equally important. Image
16/ “Studies of identical twins place the genetic influences on longevity at between 10 and 25 percent which by any estimation is surprisingly low.”

Our DNA is not our destiny.
17/ From learning from yeast to learning from trees. I am sensing a pattern here. Image
18/ Real Life terminators. Image
19/ Aging is a disease. Image
20/ This is what being old feels like physically. Image
21/ We are living longer, but at what cost. Image
22/ Cigarette smoking increases chances of developing lung cancer by 5x. Here’s how it works 👇 Image
23/ “Though smoking increases the risk of getting cancer by fivefold, being 50 years old increases your cancer risk hundred fold. By the age of 70, it’s a thousand fold.

Not just cancer, valid for heart disease. And Diabetes. And Dementia. The list goes on & on.”
24/ It’s that simple. Image
25/ The 1st & most probably the last genuine Self Help guy. Image
26/ Intermittent fasting (IF) works.

“Go hungry for an entire week every quarter.” ~ @PeterAttiaMD Image
27/ Your diet probably needs to look a lot like a rabbit’s lunch than a lion’s dinner. Image
28/ Something in which protein shake drinkers be interested in. Image
29/ Wear one less sweater to live longer. Image
30/ Once you understand how cells actually work, they are the most amazing things. Image
31/ The possibilities with Gene Therapy 🧬 are 🤯 Image
32/ ‘Precision medicine’ is catching up.

Not just what works for most people most of the time. Image
33/ The power of precision medicine & why do we need it. Image
34/‘It won’t be long before prescribing a drug without first knowing a patient’s genome will seem medieval.’

Enter Pharmocoepigenetics: We all don’t respond to medicines in the same way. Image
35/ The book predicted the current Pandemic. ImageImage
36/ “Epidemiologists say a fast moving airborne pathogen will kill more than 30 million people in less than a year and they say that there is a reasonable probability that the world will experience such an outbreak in the next 10-15 years.” ~ Bill Gates in 2017.
37/ Be careful what you wish for. Image
38/ Even Nobel Laureates & Billionaires can underestimate compounding. The thing that differentiates us & them is that they are quick to change lanes. Image
39/ Reminds me of Anton Ego’s speech in the Pixar movie ‘Ratatouille’: Image
40/ Start working on getting rich if you want to live longer. Image
41/ All the age related advances in the next decades will be expensive. Image
42/ This will happen when we face a population explosion 🚀 Image
43/ “In 1800, the global literacy rate was 12%, by 1900 and it was 21% & today it’s 85%. We now live in a world where more than 4 out of 5 people can read, the majority of whom have instant access to essentially all the world‘s knowledge.”
44/ This is something to watch out for: the working age population crisis in most countries could be solved. Image
45/ If you think extending your lifespan isn’t for you, Read this. Image
46/ A dab of optimism goes a long way in the discovery of the new 💫

Wish I read this book earlier.

Time to make some changes to the epigenome.

Aging is a disease. (X9999)

The actual research is wild. Every time you push down a feeling, your brain has to choose between suppressing that emotion and recording what’s happening around you. It picks the suppression. The memory doesn’t get saved.

A 2000 Stanford study confirmed this: people told to hide their emotions while watching a film remembered far fewer details than people who just reacted naturally. Suppressing emotions uses up mental energy, and that leaves less brain power for saving new memories.

Brain scans show why. A 2012 study found that suppression quiets the hippocampus (your brain’s memory-recording center) right when it should be saving information. The two brain regions that normally team up to lock in memories stop talking to each other.

Over time it gets worse. Suppression keeps cortisol (the stress hormone) elevated, and cortisol shrinks the hippocampus. Chronically stressed people can lose 10 to 15% of its volume. Just three weeks of high cortisol can shrink the tiny connection points between brain cells by about 20%. The good news: studies show this shrinkage can partially reverse once stress levels drop. Not necessarily permanent.

A Finnish study of 1,137 older adults tracked over roughly a decade found that habitual emotion suppressors had nearly 5x the risk of developing dementia, even after controlling for genetics, smoking, obesity, and education.

There’s a better way to handle emotions that doesn’t cost you your memory. It’s called cognitive reappraisal: instead of bottling the feeling, you reframe what’s causing it. (“This meeting isn’t a threat, it’s practice.”) A 2003 Stanford/UC Berkeley study found reappraisers had more positive emotion, better relationships, and higher wellbeing. Suppressors got the opposite on every measure. And reappraisal carries zero memory cost.

The difference comes down to timing. Suppression kicks in after the emotion has already fired, so your brain is fighting its own response while simultaneously trying to record the moment. Reappraisal changes how you interpret the situation before the emotion fully activates. Same event, same person, but your hippocampus stays free to do its actual job: recording your life.

A lot of people are asking on how to reverse this so here’s what the research actually says.

The hippocampus (the part of your brain that records memories) can physically recover once you stop chronically suppressing. A study on patients with extreme cortisol levels found up to 10% volume recovery after their stress hormones normalized.

Three things that speed this up:

Exercise. A 2011 University of Pittsburgh study found that adults who walked 40 minutes, 3x a week for a year grew their hippocampus by about 2%, effectively reversing 1 to 2 years of age-related shrinkage. Walking. Not even intense exercise.

Reappraisal over suppression. Instead of pushing a feeling down, reframe what caused it. “This isn’t a disaster, it’s a setback I can fix.” A Stanford study found this costs your brain zero working memory, so your memory center keeps recording normally. Same situation, completely different outcome for your brain.

Sleep. Deep sleep is when your brain consolidates memories and clears cortisol. Chronic suppressors tend to have worse sleep quality because unprocessed emotions keep the stress system activated at night. Fixing the suppression habit improves sleep, which improves memory encoding, which compounds over time.

The damage from years of suppression isn’t a light switch (as expected). But the brain is more plastic than most people realize. The recovery starts when this pattern stops.

Top 10 prompts I use in Screener AI that do hours of research in minutes 🧵

Sharing as requested by many friends. Honestly, I should have charged for this. Steal this.

Pro Tip: Always use the Expert Intelligence feature. It's a bit slower and more expensive, but the depth of the answers is night and day.Image
Prompt 1: The Earnings Quality Detector

"I want you to do a deep forensic comparison between the company's reported Profit After Tax and its Cash Flow from Operations over the last 5 years. Pull the exact numbers for each year side by side. For every year in which PAT grew while operating cash flow declined, stayed flat, or grew significantly more slowly than PAT, I want a full breakdown of the causes of the divergence. Specifically, did trade receivables grow faster than revenue that year? Did inventory levels spike relative to the cost of goods sold? Were there any changes in depreciation or amortization policies mentioned in the annual report? Were there exceptional or non-recurring items inflating profit? Did the company capitalize expenses that were previously expensed? Go through the cash flow statement line by line for those divergent years and explain every major adjustment between net profit and operating cash flow. Also, check the conference call transcripts—did any analyst question the cash flow situation, and how did management respond? If management gave any explanation for weak cash conversion, pull the exact context. Finally, calculate the cumulative PAT vs. cumulative OCF over the entire 5-year period and tell me what percentage of reported profits actually converted to cash."

Why this works: Profit is an opinion. Cash flow is a fact. This prompt doesn't just flag the divergence. It forces the AI to trace exactly where the cash is leaking. You'll catch aggressive revenue recognition, channel stuffing, inventory buildup before a demand slowdown, and policy changes designed to inflate reported earnings. The cumulative conversion ratio at the end is the killer metric. A company that reported 500 crores of PAT over 5 years but only generated 300 crores of OCF has a 60% conversion ratio. That missing 40% went somewhere, and you need to understand where.
Prompt 2: The Management Consistency Scorecard

"Go through every con call transcript available, starting from the oldest. For each call, extract every specific forward-looking statement management made -- revenue growth targets, margin guidance, capex timelines, capacity expansion plans, new product or geography launches, debt reduction commitments, return ratio targets, order book projections, and client acquisition goals. Be exhaustive. Then, for each of these promises, track them into the subsequent quarters and check whether they were actually delivered. Build me a detailed scorecard in a table format: Column 1 is the con call date, Column 2 is the specific promise or guidance, Column 3 is the timeline they gave, Column 4 is what actually happened, Column 5 is a verdict -- Delivered, Partially Delivered, Missed, or Not Yet Due. I also want you to flag any instance in which management quietly stopped discussing a previously announced initiative without ever addressing what happened to it. Those silent abandonments are as telling as outright misses. At the end, give me an overall trust score -- what percentage of trackable promises were delivered or exceeded?"

Why this works: Everyone reads the latest con call and gets excited by the next quarter's guidance. Nobody tracks what management said 6 or 8 quarters ago. This prompt builds a trust database for you. A management team that consistently delivers on 80%+ of its commitments deserves a valuation premium. One that delivers on 40% is essentially guiding the market into buying a story that never materializes. The "silent abandonment" flag is particularly powerful: management loves to announce bold plans during bull runs and then pretend they never said it when things get tough. This prompt catches that pattern.

Started a week ago, not knowing how to write a single line of code

I wanted to read the Bhagavad Gita daily, but couldn't find an app that felt right. So I built one.

Ended with a full iOS app live @10minutegita on the App Store:
→ 239 daily readings of the Bhagavad Gita
→ Original Sanskrit shlokas + transliteration
→ Verse-by-verse translations & commentary
→ Personal daily reflections
→ Streak tracking with calendar heatmap
→ Shareable verse cards with 8 gradient themes
→ Hindi & English bilingual support
→ Light/dark mode, adjustable fonts
→ Completely offline after download

Total cost: $200 Claude Max Subscription + $20 ChatGPT Pro Subscription + $99 Apple Developer fee
Lines of code I wrote: 0

Claude Code wrote everything. I just described what I wanted in plain English (non-technical background). Codex reviewed it. Now it's live on the App Store.

The barrier to building isn't coding anymore. It's just knowing what problem you want solved.

There's this perception that IDFC First Bank has only one leader, Mr. V Vaidyanathan

Let me put rest to this mistaken opinion.

A thread 🧵👇
1/ Madhivanan Balakrishnan, COO

MSMEs need to be connected to digital entrepreneurs

Using E-marketplace, GEMS, & GST, bankers are augmenting the underwriting with these

70-75% of the retail lending 100% digital: 4-4.5 lk loans/month (digitally)

OCEN 🚀
2/ Sumit Madan, Head- Retail Liabilities & Branch Banking

The only bank in the country with an integrated app: For CA & SA (Aids MSMEs)

The startup ecosystem is uniting all Indians

Among the highest rates for Debit cards & the lowest for credit cards

IRFC: Business Analysis 🚂

A Regulated Monopoly Lender with zero NPAs & growing faster than HDFC & ICICI Banks

I authored this on Dec 2021 when the stock was barely talked about, posting it today to improve my engagement numbers on Twitter ✨

A Thread 🧵👇
1/ History.

IRFC was established in 1986 as a dedicated market borrowing arm of the Indian Railways, registered with the RBI as an NBFC (Systematically Important)

But why do Railways need them, can't they directly ask for funds from the Ministry of Railways (MoR)?
2/ Here, enters the Government according to whom raising money from the open market is not the duty of MoR, it is the duty of the Ministry of Finance (MoF)

which didn't want to act as an intermediary & thus IRFC was born to raise money& fund the capital needs of Indian Railways.
