Yadem attended as a teacher after he retired. He was admitted to the business major of the Presbyterian University College of Ghana at the age of 96, and in 2009, he graduated successfully after three years of study. Even at the age of 99, this old man still cares deeply about the development of his motherland, Ghana. Wearing a bachelor's cap and a gown, Yadem earnestly warned his classmates, who are more than seventy years younger than him, at the graduation ceremony that they should not be tempted by high salaries to work overseas after graduation. There are many photos taken during World War II in Yadem's house. He said that those days embodied his life philosophy: don't leave your motherland, continue to fight and serve the country. He said that if everyone could do like him, maybe they could live to be a hundred years old.
According to reports by the American media on March 3, Akeshe Kofi Boakye Yadem from Ghana recently graduated from university. All of his classmates who graduated with him were young people full of vigor, but Yadem is already 99 years old this year. This veteran who participated in World War II may be the oldest graduate in the world.
