Triune Brain Theory: Explained in Simple Terms

What is the Triune brain? What are the three levels of the brain, according to the Triune theory? In the Triune brain model, the brain is divided into three levels: the neocortex, the limbic system, and the reptilian complex. According to this model, each level is self-contained in the sense that it doesn’t interact with the other two. In reality, the whole brain is interconnected, so this model should be taken metaphorically, not literally.

What Happens When You Fast?

What happens when you fast? How long does it take to start losing weight when fasting? What are the common side-effects of fasting?

Why Do We Age and Die? Biologist Explains

Why do we age and die? Do we really age and die to make room for our descendants? Humans have always accepted aging as a fact of life, but relatively few people have questioned why it has to happen. The oldest theory, dating back to Aristotle, is that we age and die for the good of the species, to “make room” for the next generation.

Is it possible to cure aging? How can human societies adapt to the world without aging? According to biologist David Sinclair, it’s inevitable that we’ll cure the disease of aging. Further, he believes that we can not only cure aging but also create a world that’s able to support an undying human population. It will require major changes in how we think about almost every aspect of society, but Sinclair says that it’s not only possible but necessary to do so.
