Dear editor In this era of a modern pandemic of this new millennium, called as COVID-19, which has left no borders of the human world untouched on this planet. It is a timeless thing to be a witness to this future historic event of this millennium. The world has moved into the era of globalization with cutting edge technology and highly advanced therapies for some of the most complex human diseases. We can now identify the extremes of nano causes of illness and human diseases and intervene in the nano world. Putting intravascular stents, breaking down calcium plaques in the vessels, transplanting human hearts, utilizing artificial hearts, devices such as ICDs for life-threatening arrhythmias are just very few examples of incredibly advanced treatments for improving human health and treating illness. These highly advanced therapies that exist now were once only a dream of some crazy beings, decades and centuries ago. We have touched human lives in the most possible nano routes. We can fathom the DNA and RNA technology. We now have the vaccines for Covid-19 using the mRNA technology which is a huge technological advancement. Despite all of these, we have to remain that humble being since we still do not know a whole lot about lots of things. The fact that we are living in a world of a deadly pandemic despite persistent heroic measures worldwide from multiple sources for the past two years tells us that we are merely insignificant beings.
