In <What Is Life?>, written by Lynn Margulis and Dorion Sagan, there is an expression, “Independence is a political term, not a scientific term.” Independence is the state in which a person can live alone without help or influence from others, using their own strength and ability. The condition of being physically separated from the community is called “isolation.” Independence and isolation are different. Isolation should not be mistaken for independence. To exclude influence and secure autonomy is independence, while deliberately cutting off relationships is isolation. Independence is based on achievement; isolation is based on hurt. To grow, you must be independent, not isolated. - 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”
