I must present my studies several times a year at congress or workshop because I am a medical investigator. March this year, I went to Vienna for speech at European Congress of Radiology. Next week, I will orally deliver my study about comparison of MRI with CT of chest in Tomographic Imaging Workshop in Tokyo.
At day time, I am very busy for routine work then I must assemble the data for the study at night. During about two weeks before a presentation at any workshops, I must shorten my sleeping time, which is often less than two hours.
