Olfactory: Charles Spence, the world-renowned scientist who invented gastrophysics, explains that although aging diminishes all human senses, most people believe they would miss sight the most. However, according to quality-of-life indicators and suicide rate data, losing the sense of smell is actually more harmful than losing sight. Even if we lose sight as we age, we can still find comfort in hearing the voices of loved ones and recalling memories. In contrast, when we lose our sense of smell, there is no way to recreate those experiences, and memories of scents cannot be imagined or recalled in abundance. To enrich our lives, we should focus on increasing our scent experiences, as the ability to smell is a key contributor to happiness. - Joseph’s “just my thoughts”
After the Human Genome Project mapped our DNA, we discovered that gene expression and activation patterns can be altered and passed on to future generations without changes in sequence, a phenomenon known as epigenetics. This means that even identical twins, whose genetic information is almost 100% exact, will have different gene activation patterns based on their environment and experiences and pass on their traits to the next generation. A typical phenomenon is methylation (CH3), which is the addition of one carbon and three hydrogens to CpGs in mammalian sequences. Depending on this methylation, although someone inherits the same gene sequence, certain genetic traits can be activated or deactivated. It is also believed that a unique upbringing or education in life influences this phenomenon. Of course, as with any scientific phenomenon or technology, the cause or effect may change over time, but if there's a lesson to be learned, this is one of the most important reasons not to ...
