I'll See You in Twenty Years

People have dreamed of returning to their youth to correct their errors and naivet. Dr. Frank Dodd acquired that chance but for a different reason. He and his wife, Dr. Beverly Dodd, are retired professors from a small north Florida College. They had just started enjoying retirement when they found Beverly had inoperable cancer and would soon die. Frank bemoaned the fact he hadn't insisted on Beverly seeing a doctor a year earlier when she could have been cured.
While in a chat room two fellow scientists heard Frank discuss his regrets at not getting his wife help in time and how he wished he could go back in time to court and marry her again, only this time get her to the doctors in time to be cured. The two scientists have been doing experiments in time travel and knowledge transfer between brains. Frank agreed to be used as a guinea pig to be sent back to the time of his youth and to implant his knowledge into himself as a boy. He arrives in 1941 with computers and other modern equipment to sell to the government and industry and invest the proceeds for the benefit of all three while living his life over, striving to have the same experiences and doing the same things from his former youth, but this time avoiding the mistakes of his former life. The dilemma occurs when he falls in love with a woman he meets in this new life. Should he remain single and wait for 15 years to meet and court his wife again or marry the one he falls in loves with during his present time.
