Living in the city, I've come across a lot of people, from young kids to really old men and women, who has set up their work area near the side-walks of city roads. Some sell fruits, like lemons and apple, while some make and sell fresh bhajis and fries during the early evening hours. There are some selling fish, while some selling vegetables. Those who couldn't find a spot for sale, carry their toys and small merchandise and try to sell them to the drivers of vehicles while they stop at the red traffic signal at city junctions. 

Am sympathetic, yet amused when I see septuagenarian's carrying the remains of their days work, which are, quite often two or more heavy bags, that they somehow balance using their arms, and head, and without even a single faulty step, go about their way.
