Humans have relied on horses for transportation for a long time. Horses are anatomically designed for running, are strong, and possess excellent endurance. However, the reason this horse was chosen as a means of transportation for humanity is that its back does not shake much when it runs, which is also a crucial factor. Observe a horse’s back as it runs. Regardless of how well a horse runs, for a person to ride it, there must be minimal shaking. If running well is the primary function, a smoother ride becomes a secondary consideration. However, the world often prioritizes only the primary function, overlooking the significance of these secondary functions and their roles in actualizing that primary function. - 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”
