An education doctor! Lee TV

Hello, I'm Dong-Hwan Lee, a medical doctor living in Korea. My major is family medicine, function medicine and mind-body medicine. I also received a master's degree in education engineering and a Ph.D. in business administration. Business administration has done research related to job stress in the field of personnel organization.
Starting with the study of a person's body that started in medicine, I am studying the performance of a person with job stress.
I am constantly giving lectures on health, chronic fatigue, and stress at many companies, local governments, and institutions.
On this channel, we are uploading videos of how we live healthy and happy lives. Please watch it a lot. Thank you.
