Who Is Really Advanced?

To fight against Corona pandemic, all are advised to be vaccinated; Also, all have to wear face mask, maintain social distancing and wash hands; But there is no surety that they all are going to be effect but for protection; Something is done to create hope and confidence to people, it seems, that's all! Precaution only seems to save people against infection of any disease ever; That is by discipline all can manage themselves against infection sure; Disease-less healthy life only can be called civilization in the modern world; If we have not achieved that status of life in this world, it is meaningless! Modern world means we should be advanced in all respects to be civilized; We should not have any fear whatsoever by our knowledge and power....; But if we are afraid of anything even now like in the past means we are useless; When are we going to achieve that kind of status too be confident ever! All living beings around us in Nature are healthy and happy except humans; Who are clever and wise, though we call ourselves to be advanced and modern?
