The unrealistic expectations that some people have are the myth. Immortality is more attainable than most people imagine. This article will discuss the steps to achieve immortality. From why we die and age in the first place to the specifics of how we die is a question humanity has long considered? There will be three sections on how we can achieve immortality. The first challenge of immortality would be to cure microorganism diseases, the second physical injuries, and the last is to put an end to natural deaths, such as aging. Say no to plagiarism.

Lifespan has increased and will continue for the foreseeable future. According to Harari, Y.N., Purcell, J., and Watzman, H. (2019), genetic engineers have managed to double the lifespan of Caenorhabditis elegans worms. What stops us from doing the same with humans? Roser, M. (2013) statistics show that human lifespan has doubled since 1900 and the latest medical and scientific advances are promising in this regard. Life Expectancy Humanity has been able to exceed expectations and achieve what was previously thought impossible. In the past, people thought that diseases were a necessary and mysterious evil, but now we think of them as technical difficulties that can be overcome. Scientists and doctors may not be directly pursuing immortality, but medical progress is opening new doors in unknown and exciting directions. Winning The War Over Bacteria Harari, Y.N., Purcell, J., & Watzman, H. (2019) mention in their book that in 1700, 150 out of 1000 newborns died during the first year of life and in England a third of all children died before reaching the age of fifteen. Currently, only 5 out of 1,000 newborns die during the first year of life and only 7 out of 1,000 die before the age of fifteen. Decades ago, parents would have dozens of children in the hope that one would survive, and they accepted it as part of their daily lives. Who knows how our reality might change in the coming decades? However, our path is not smooth. As medicine improves, bacteria develop. One of the challenges we are facing is superbugs, or superbugs, which are bacteria that develop resistance to antibiotics; simply put, antibiotics are no longer that effective. However, scientists are working on treatments that will contain and hopefully prevent superbugs. The new treatment was included in an article published in CNB, C: The way this new strategy works is that the drugs are designed to target and disable the cellular machinery that causes these bacteria to resist antibiotics. If this approach is combined with other treatments, the likelihood of bacteria developing resistant bacteria could drop to zero. Correcting our defects We don't always die from an external cause. Sometimes, it's just our bodies. For example, cancer does not come from the outside, but comes from the inside. Cancer can be triggered by the environment, but it can also be a simple mistake in the DNA of our cells that causes them to harm us instead of helping us. So, after protecting ourselves from invading pathogens, we must correct the errors that occur within us. We could share the defects of oursbody in mutations and aging. First, the mutations. Mutations could occur in two ways: somatic mutations and germline mutations. The somatic mutation occurs in normal cells of the body and affects only one part of the body. On the other hand, germline mutations occur in sex cells during reproduction, then affect the entire body of the new offspring. Repairing somatic mutations could be a challenge because changing the genes of one cell does not change the DNA of other cells. However, a modified DNA in a germ cell would spread throughout the body, because this cell will divide and divide until it forms the entire body. If we want to alter the DNA of a germ cell we will have to face ethical questions, because we would have to genetically engineer human embryos. I mentioned this because the probability of making a mortal man immortal is less likely than that of an immortal infant. We could genetically engineer a cell to divide, but it would be much more difficult to genetically engineer the trillions of cells in an adult body. So, if we had the ability to modify an embryo's DNA, how could we help it escape death? Our DNA has a protective coat called a telomere at its ends. Every time our cells divide, they lose some of their DNA, and telomeres are repetitive genes that serve no purpose other than to delay the process of damaging our DNA. Every time a cell divides, its telomeres get shorter and shorter until they reach its DNA, damaging it, causing a deadly error. The molecular fountain of youth is finding a way to lengthen telomeres or prevent them from shortening. A Replacement Some people think that if we cured all diseases and genetically modified our DNA we would be immortal. In contrast, the Fountain of Youth would not prevent environmental or physical accidents. In other words, even if we cured all diseases and put an end to aging, we could still die. A car could hit us or a bullet could pass through our heart. In these cases, death may seem inevitable. However, we could replace our damaged organs with artificially made parts. There are two ways we could save lives through artificially created body parts: the first is to replace damaged limbs with inorganic prosthetics, the second is to fabricate or 3D print internal organs with living tissue. Biomanufacturing involves growing living cells outside the body to create tissues and perhaps organs. 3D printing, a recent technological device, is also used for medical purposes. This means adding layers of material on top of each other to create the desired design without the need for molding or an expensive factory. There is already a working 3D printed heart that beats and pumps, and you can explore it more on this website: Medical 3D Printing: Discover the 3D Printed Heart. Once upon a time, people thought that the heart was magical and could not be replicated. Here we are, printing a heart that could replace a real one. One day we may be able to upload our consciousness onto entirely man-made bodies. Yes, a robot with a human mind with all its memories and intelligence. However, if the robot behaves like a human, how can we know if it feels like a human? We will never know. Just like we can't know for sure that the people around us are actually real. Some might argue that we could observe human neural activity and demonstrate brain function. However, this does not prove that they have a conscience, and how can one do so
