that guy in yellow has sponge in his chak (dont ask me how do u know, its my guess) so he can sit in the streets whole day and whole night , but the poor others on his sides dont know this trick, they sit there whole day and at night they have a chak pain but they have to sit there, because its their job, they know nothing more than that (though many are poets, writers, singers, journalists) thats why that guy in yello is more active than others they did have a great role in people movement II but too much of anything is bad for health!!!!!!!!!!!
