4600ల సంవత్సరాల మెట్రో సిటీ మిస్టరి | 4600 Years Old Advanced City Mohenjo Daro. [Telugu] India FACT

A well-planned street grid and an elaborate drainage system hint that the occupants of the ancient Indus civilization city of Mohenjo Daro were skilled urban planners with a reverence for the control of water. But just who occupied the ancient city in modern-day Pakistan during the third millennium B.C. remains a puzzle.

It's pretty faceless, says Indus expert Gregory Possehl of the University of Pennsylvania in Philadelphia.

The city lacks ostentatious palaces, temples, or monuments. There's no obvious central seat of government or evidence of a king or queen. Modesty, order, and cleanliness were apparently preferred. Pottery and tools of copper and stone were standardized. Seals and weights suggest a system of tightly controlled trade.

The city's wealth and stature is evident in artifacts such as ivory, lapis, carnelian, and gold beads, as well as the baked-brick city structures themselves.

A watertight pool called the Great Bath, perched on top of a mound of dirt and held in place with walls of baked brick, is the closest structure Mohenjo Daro has to a temple. Possehl, a National Geographic grantee, says it suggests an ideology based on cleanliness.

Wells were found throughout the city, and nearly every house contained a bathing area and drainage system.

How to fix a broken heart | Guy Winch

At some point in our lives, almost every one of us will have our heart broken. Imagine how different things would be if we paid more attention to this unique emotional pain. Psychologist Guy Winch reveals how recovering from heartbreak starts with a determination to fight our instincts to idealize and search for answers that aren't there -- and offers a toolkit on how to, eventually, move on. Our hearts might sometimes be broken, but we don't have to break with them.
