Only when there is a surplus can new things be created. Surplus means having more than what is necessary. Creating something new requires an initial investment in advance. Whether it’s labor or capital—that is, whether labor is purchased with capital—energy can only be used for new work if there is a surplus. Only with prior investment can something entirely new, never seen before, be made. The existence of something that did not exist before in this world results from someone putting in their surplus first. - 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”
