We have built a society where many elderly people are entirely dependent on others to go out.

Dr Asha Islam Nayeem, a professor in the Department of History at the Dhaka University, has a heart-wrenching story.

In many cities around the world, elderly people literally cannot cross the road because the timing on crossing signals is too brief. At least we don’t have that problem in Dhaka, if only due to the absence of functional traffic lights.
