How many neurons does a human brain have? Are larger brains smarter brains? Do larger brains have more neurons in them? Does the size of a brain increase with the size of the animal? How much energy does a brain consume, and why is this important? Are there limits to how many neurons a brain can contain?
These and many other questions are tackled in this particularly informative TED talk. Take a look:
Sleep, while very much neglected in today’s society, is extremely important for the physical and mental health of each and every one of us. The lack or inability to get sufficient sleep can lead to problems like poor memory, poor judgement, less creativity, increased impulsiveness, but also increased hunger, diabetes, stress, high blood pressure, immunity problems, etc. This highlights part of why it is so vital to get qualitative sleep. Sure you might gain a couple of hours a day by sleeping 5-6 hours, but you’re most likely reducing your lifespan by much more than you are gaining. Plus, I’m pretty sure you would prefer to wake up relaxed and start a new day feeling you have the energy to tackle whatever it throws at you instead of getting out of bed and feeling depleted and frustrated even.
You can find a quick overview of some of the positive effects good and sufficient sleep can have in this chart in the video.
Seriously, what is unhealthier? Salt or sugar? And yes, I know that in a way these are just headlines, but there is clearly some truth behind it all. So in that case, what is the right amount of salt or sugar? I’m pretty sure it’s not 0, but I’m also sure it’s not far from 0.
What makes a good doctor (MD)? Or what makes a great doctor? Is it only the physical healing, the fixing of these tangible hypercomplex systems we call bodies? I’m not sure… but I think if so, that would make many doctors resemble to fascinated repairmen.
Well, luckily there’s also a rare breed of doctors that also touch the human soul. Doctors, that throughout their careers, have managed to not only heal affections, but to truly change something, to influence the hearts and minds of people around them.
In his over 50 years of practice and surgeries on children, he proved an outstanding dedication to the principles of medicine and an excellent surgeon. He was offered countless positions in other countries, and was at one point in time considered one of the best child surgeons in eastern Europe. Still, he always remained faithful to his promise to help whenever and wherever he could. So much so that he almost never had time for himself. He used to spend days and nights uninterrupted in the hospital, never having time to focus on the material side of life. He didn’t even find the time to mourn his two sons that left the realm of the living before he did.
Current estimations suggest that he executed over 50.000 surgeries on children during his entire career, with a high rate of success and many solved “inoperable” cases. I was one of those 50.000.
The following is an interview (in Romanian) highlighting his situation in his last years of life. One of his few joys in this period remained the hundreds of letters of gratitude he received from every corner of the country, and of the world.
Dr. Oarsa Zeno (Zenobiu) is another remarkable doctor and artist. Besides being a great doctor, he was a renowned painter and an eternal teacher… teacher of common sense, of kindness.
I’m lucky that I had the privilege to encounter both these outstanding men during my lifetime. Besides the medical impact they had on me, I had the opportunity to bathe in their warmth, to listen to their stories and learn about true nobility. Thank you.
Yes, believe it or not, mosquitos are the creatures that kill most humans every year. Just think at the share numbers of malaria infections or Dengue fever. I’ve been also partly made more aware of this situation during my recent trips in various corners of the world.
Therefore, I was even more impressed with the results highlighted in the following talk about fighting mosquitos and the corresponding diseases they carry. I hope to hear increasingly more about this genetic solution, that seems to be extremely effective and much less harmful than the previous chemical-based ones.
Opportunities for us to tackle our problems and fears? Of course, this is not the case for all people with depressions; but what Neel Burton is suggesting is that some things are incorrectly or unnecessarily diagnosed as depressions.
I particularly like the final part of the video: “People in the depressive position are often stigmatized as failures or losers. Of course nothing could be further from the truth. If these people are in a depressive position, it’s because they have tried too hard or taken on too much. So hard and so much that they have made themselves ill with depression.[…] So if they are failures or losers, this is only because they’ve set the bar far too high. They could have swept everything under the carpet and pretended—as so many people do—that all is for the best, the best of possible worlds. However, unlike most people, they had the strength and honesty to admit that something was a miss…”
Finally, I—at least partially—agree with the following quote: “Happiness is beneficial for the body but it is grief that develops the powers of the mind.” – Marcel Proust
