Research Has Delayed Value
Research is also not perfect due to its sometimes delayed value. For instance, health scientist may conduct research for decades, attempting to find a cure for such diseases as breast cancer, heart disease, and colon cancer, only to turn up short again and again. However, instead of going back to the drawing board, researchers strive to improve upon the knowledge that has already been gained by such research. For instance, some cures for a disease have taken decades to discover, including measles, smallpox, and polio. These discoveries, however, have been only a springboard for further research which will mostly likely require decades (if not centuries) before other cures will be found.
And other cures will definitely be found as more discoveries are made and knowledge increases decade by decade.
