One of the key principles of money is ‘opportunity cost.’ It means that when I buy something, I have to give up something else in return. We think we buy because we need something, but we often forget that we could buy something else instead. We rarely consider ‘opportunity cost’ when making a purchase. We do not compare other values against our needs. Buying something means giving up something else, but we often don’t realize it. When we spend money, we should also consider the ‘opportunity cost’; yet, in reality, we aren’t trained to do so. By making a purchase, we bypass the value comparison that may not offer any additional benefits. Maybe it’s because we lack knowledge, or perhaps the idea isn’t appealing. - 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 ...
