Throughout the history of human development, everyone has lived longer; a baby born in 1850 could only expect to live 35 years, yet the average life expectancy of the current human population in general can exceed 75 years.
How then humanity overturned the prophecy of mastering our life calculation ruler relies heavily on the intrepid scientists of the past, present, and future fighting in the laboratory, especially microbiologists such as, for example, Anthony Philips van Leeuwenhoek (who invented the microscope and observed "animal" (small animal) microbes (bacteria and Protozoa), Louis Pasteur (who coined the term "fermentation" and is the "father of modern microbiology/bacteriology"), Robert Koch (who proposed Koch's law, validated the germ theory of disease, and was the founder of modern microbiology) They rescued pregnant women, saved babies, fought against plague, developed vaccines, discovered antibiotics, etc., which greatly expanded human knowledge of life and microorganisms and made important contributions to prolonging human life. They have made important contributions to the extension of human life.
A tribute to the great biologists
