Five Discoveries That Extended Human Lifespan

Here are 5 scientific discoveries that extended human lifespan, 1) Clean water and sanitation

Once science linked disease to contaminated water, cities built sewage systems and protected

drinking supplies. Deaths from cholera, typhoid, and dysentery collapsed. This single shift

prevented millions of early deaths, especially in children, and raised life expectancy more

than most medical treatments. 2) Antibiotics Before antibiotics, infections were

often fatal: pneumonia, infected wounds, childbirth complications. Antibiotics turned these into treatable

events. They also made surgery and cancer therapy possible by preventing deadly infections.

This removed a huge amount of random, premature death from daily life. 3) Anesthesia and
