Volatility and Investment: The phenomenon where an asset’s price fluctuates over time is called volatility. Owning and reselling this volatile asset is known as an investment. The concept of buying and reselling an asset often causes us to overlook the fact that this process involves a trade-off between low-volatility and high-volatility assets. Cash is less volatile than stocks, and stocks are relatively more volatile. In other words, investing involves exchanging low-volatility assets for high-volatility assets and then switching back to low-volatility assets. Meanwhile, surplus profit is generated by the price differences caused by volatility. What would happen if we traded only highly volatile assets with each other? We would probably hesitate to exchange assets and might refrain from investing. In investing, there must be both low-volatility and high-volatility assets. - Joseph’s “just my thoughts”
A lifetime of tuna is about 10 years. They don't have any muscles to suck the water up and constantly have to be moving their bodies to breathe in the water. So, they can not be sleeping or resting a lifetime of tuna. Even going to sleep, tuna must keep on moving in a sleep-like state until their deaths, if they stop moving, they will be dead soon. According to the attribution, tuna can swim in water at over 100 km/h speed, they need so many other fishes as foods to supply the wasted energy for this fact. The tuna is paid for the huge price of becoming a top-rated predator. But I'm not a top predator, so why do I eat so much? - Joseph’s “just my thoughts”
