<Note to Self>
1.
They are part of volunteer staff, aren't they?
The Sochi Olympics will take place in about 2 months. No more than 2 months!! Selections just 2 months before the Olympics?? I wonder if it's normal.
2.
The successful applicants ratio is around 30%. I somehow feel that it's too row. That's about normal?
3.
In the Tokyo Olympics, should all volunteers be Tokyo residents?
