When I was a third grade student in high school, it was my first time to donate blood. As far as I know, korea = Korea has suffered from the lack of blood donors. To promote blood donations, blood centers visiting high schools by blood centers were = was quite common, when I was young. It was not forced one, it's a voluteer = volunteer job. I just did that at a nurse's room in a = our school. After I filled out the checklist that was quite simple than currenr one as I remember, I started the blood donation. It took about 20 minutes. I took a rest after donating blood. To rejuvenate the blood donors, a milk and a bread were provided. I was so satisfied with that snack not sharing.
