What is common between a chartered accountant, a dental surgeon, an air force officer and an undergraduate student?
They are all volunteers for the forthcoming Commonwealth Games.
Taking time out from their busy, markedly-different schedules, many such volunteers, across the city, are pitching in to make the Games a success.
Soon, though, they will be seen on Delhi roads, dressed in white t-shirts, blue jeans and caps, managing traffic and guiding commuters.
And when the Games get underway, traffic volunteers will spread across the city, along lanes marked for Games vehicles.
They will also fan out along various Games venues, in a bid to help manage traffic.
A month ago, the Delhi Traffic Police were apprehensive about managing traffic during the Games, with just 3,500 policemen. Now, though, their confidence level has gone up.
"We now have a bunch of 1,200 dedicated youth to help our men," said Ajay Chadha, special CP (Traffic).
"The volunteers will front-end our men when we need to guide or assist foreigners," said another officer.
Having undergone many rounds of training in traffic management, the volunteers are now familiar with Games venues, routes and duty points.
"During the Games, if our participation helps manage traffic better, why not?" said Preet Kamal of Hari Nagar, a B.Tech student.
History (Honours) student Anjali Kumari is excited, as, "Some years later, the Games will be part of history and I will be proud to have been a volunteer."
