Marathon runners rarely smile before, during, or after the race and usually have a very serious expression. If there were aliens, everyone who participated in the marathon might be considered a criminal because they don’t look happy. Humans think they only enjoy happy and joyful work and avoid hard, painful work, but in reality, human motivation is more complex. Even if something is hard and painful, it’s not as simple as just participating in marathons. Humans do not act solely based on joy and happiness. If humans can find meaning in life and experience progress even when it’s difficult, they are willing to do it. - 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”
