I am a Hepatologist.
Arguably, I care for the sickest group of patients in medical practice – end stage liver disease.
I see death almost every day in my ICU.
Some are natural deaths, leading to multiple organ failure triggered by a failing liver.
Some are decided. The family decided to pull the plug. They decide it was time to let go.
And every time, I see the heart rate drop, the blood pressure fall and the electrocardiogram go flat.
And I wonder. What goes on inside a dying brain?
Was it a small black hole, that gets bigger and bigger and then engulfs the field in darkness as the heart shuts down taking the brain away with it?
Or was it just all light at the end of the tunnel and then darkness, once the destination had reached?
A group of doctors did something strange. Something unimaginable.
And it led to them witnessing something melancholic, but beautiful.
They went inside an ICU. Saw that four patients were unconscious.
They were not clinically dead, yet. And not brain-dead. But were comatose.
They were kept alive by a machine that pumped oxygen into their lungs.
Three had brain injury due to cardiac arrest. One had haemorrhaged into the brain.
All were unresponsive for a very long time and sadly, the family decided to pull the plug on them.
To let them go away, peacefully.
But before they did that, the loving family did something bittersweet. They signed a document which was made by the group of doctors, allowing them to study their beloveds’ dying brain.
The group was led by Dr Jimo Borjigin of the Department of Molecular and Integrative Physiology, University of Michigan School of Medicine, Ann Arbor at Michigan.
The doctors fitted machines to the heart and brain of the dying patients and then withdrew their life support by removing the breathing tube.
Immediately after the tube was removed, the brain activity did not show anything different.
But as the brain got closer to death, about 300 seconds before death, a power surge. And it occurred in the regions of the brain which was associated with conscious experience. Like the dying was suddenly yearning to live.
And make no mistake, these were not “some bursts” of electrical activity that happens when the brain cells withered away without oxygen. This was a special kind of activity.
These power surges increased connectivity in a region in the brain called posterior cortical “hot zone” – an area crucial for conscious perception – when it came to just before dying, the brain cells were having a cross-talk, not dying away into oblivion.
They were passing final messages to each other within the regions of the brain, while the physical body lay, limp and motionless.
And the doctors were heartbroken – because the final electrical pattern of surge that the dying brain was showing was the similar to those seen in dreaming humans.
All the patients in the study died.
But before they died, they taught us something.
That even in death, our minds are resilient.
That we clutch at only everything that is good.
What were they dreaming of?
A husband, about his loving wife?
A mother, her children?
Children, their parents?
Or maybe a scene from a movie that changed you?
Or a song under a starry sky?
Or a pet who loved you unconditionally?
We will never know.
But know this, even in death, the mind conquers – with dreams and love, not nightmares and hate.
Remember, nothing perfect lasts forever, except in our memories.
Make good memories while living, so that we can re-live them in death.
Go hug you family, take your children for an ice cream. Walk your dog into the sunset.

Yesterday, my account was hacked for a while and strangely, my most viral tweet was deleted. So here it is, updated for 2025 for science and health-illiterates.
To summarize:
1. One whole egg with yolk a day does not increase blood cholesterol
2. Green tea does not help you lose weight
3. Jaggery, honey or sugarcane are not healthier than white sugar
4. There is no "healthy alcohol"
5. Ashwagandha does not reduce stress or help you sleep
6. Shilajit is a resinous piece of rock that does not benefit male sexual health
7. Turmeric in milk does not get beneficially absorbed in body and is lost in stool
8. You can consume fruits anytime during day or night
9. Sugarless black coffee at least 3 cups is good for fatty liver disease
10. Apple cider vinegar is good for only trapping fruit flies
11. Eight glasses of water a day is a myth
12. Pure whey protein supplementation to target recommended higher protein intake is safe for liver and kidneys
13. Magnesium supplements don't help you sleep
14. Anti-ageing is a myth
15. Herbalife products are the most common cause of liver injuries globally in the context of herbal and dietary supplements induced liver damage
16. Just because you lost weight by whatever means does not make you a "health coach."
17. Consumption of dairy along with fruits is perfectly fine
18. Yoga does not help you lose weight
19. Multivitamin a day does not improve health or prevent diseases in general. It can however, increase the risk of multiple cancers
20. Biotin does not help in hair growth or increase length of hair
21. Here are some liver supplements that you are wasting time and money on - Milk thistle, TUDCA and S-adenosyl methionine (SAMe)
22. The liver detoxes you, you don't detox the liver
23. Do not insult the kidneys by drinking yours or others urine, thinking urine therapy is going to help you live longer
24. Your favourite celebrity is always wrong about healthcare. Do not take medical advice from a pretty looking heroine or macho looking hero.
25. Virat Kohli and Cristiano Ronaldo do not drink Herbalife shakes. They just pose with it, for money
26. BluePrint is Bryan Johnson's online supplements scam
27. Covid vaccines ended the pandemic
28. Ayurveda is a pseudoscience. So is Homeopathy, Siddha, Unani, Naturopathy, Reiki, and Acupuncture.
29. Homeopathy is mostly alcohol, sometimes sugar. Other times cockroach parts.
30. You personal experience is not scientific evidence.
ஏன் திமிங்கலம்..இந்த womens’s dayய use பண்ணிட்டு corporate companies, hospitals, mallsல பெண்கள் மேல ரொம்ப அக்கற இருக்குற மாதிரி offers, discountsலாம் போட்டு business ah pick up பண்ணிடுறாங்க..அவ்வளவு அக்கற இருந்தா, வருஷம் full ah பெண்களுக்கு அந்த offer price போட வேண்டியதான

@sama How come one can expect and do all the leadership change in one day itself?
Not tried to retain?
Once said, without asking why/what accepted?
Means you were not true to act as a leader.
You let them go seems. So the plan executed well. So sad.
Congrats @miramurati
This is the kind of review I want to see for bank accounts in India. Use them for your day-to-day needs and share how they are different. I am hoping to write more such reviews in future.
