I was young when I went to medical school, but very old now.

How many years had I wasted?
I was a smart kid since I took the college entrance exam when I was at first year of high school. Some of you probably knew that at that time, just after the "gang of four" lost power, and waste of so many years of high education, and the lack of college educated people, they allowed some students to take the college entrance exam without finishing high school.
But I have wasted a lot of time though afterwards in many ways.
