Dr Frederick Banting, [ Sir Frederick Grant Banting (November 14, 1891 – February 21, 1941)] was a Canadian medical scientist, physician, painter and Nobel laureate noted as the first person that used insulin on humans. In 1923 Banting and John James Rickard Macleod received the Nobel Prize in Medicine. Banting shared the award money with his colleague, Dr. Charles Best. As of September 2011, Banting, who received the Nobel Prize at age 32, remains the youngest Nobel laureate in the area of Physiology/Medicine. The Canadian government gave him a lifetime annuity to work on his research. In 1934 he was knighted by King George V. Frederick Banting was voted fourth place on The Greatest Canadian.
In the 1920s Dr. Frederick Banting focussed his attention on the ravages of diabetes. At that time medical science offered no effective method of arresting the disease. Dr. Banting spent considerable time experimenting and studying the international literature on the subject, but every path he explored seemed to be a dead end.
One night, exhausted by still another long day of what seemed to be wasted efforts, he fell asleep. While he lay sleeping, his subconscious mind instructed him to extract the residue from the degenerated pancreatic duct of dogs. This inspiration led him to the discovery of insulin, which has helped countless millions of people since.
You will note that Dr. Banting had been consciously dwelling on the problem for some time, seeking a solution, a way out. His subconscious responded accordingly.
It does not follow that you will always arrive at the solution overnight. The answer may not come for some time. Do not be discouraged. Keep on turning the problem over every night to the subconscious night prior to sleep, as if you had never done it before.
