Mumbai street lamps

via humansofmumbai : Studying here in Poddar galli (Abhyaas Gali Path) under a street lamp is my choice and its not only mine but for many students who come here in the night to study, the main reason being the environment and the peace which this lane gives me. This place is silent and one can study whatever one want, one don’t see the time, whenever one wants to come, one comes and there is undisturbed studying here.

Thankfully there is lot less of it in the paper. The paper is very interesting as it uses Google trends as a proxy for consumer pre-purchase interest.
