Common means relatively few limits. Therefore, the common items should be inexpensive—for example, air. But just because it’s common doesn’t mean it lacks value. It simply signifies a lower price. Just because it’s almost free doesn’t mean it’s without merit. The sector a product belongs to affects the profitable connection between value and price. Daily necessities are inexpensive because they are common, but they hold significant value. If the imbalance between value and price exceeds the risks of an exchange opportunity, a profit is generated. If you capitalize on this opportunity and take a risk to purchase the imbalance, it is referred to as an investment. Opportunities always arise from imbalance. - 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”
