The Brahmaputra is considered to be among the most majestic rivers in the world. The Brahmaputra enters India in the state of Arunachal Pradesh, where it is called Siang. It makes a very rapid descent from its original height in Tibet, and finally appears in the plains, where it is called Dihang. It flows for about 35 km (22 mi) and is joined by the Dibang River and the Lohit River at the head of the Assam Valley. Below the Lohit, the river is called Brahmaputra, enters the state of Assam, and becomes very wide—as wide as 10 km (6 mi) in parts of Assam.

The Taj Mahal is almost perfectly symmetrical, in keeping with Persian and Islamic architectural principles. The minarets (towers), walls, rooms, and even gardens are all symmetrical. The Taj Mahal, one of the world's most perfectly symmetrical structures, is known for its white beauty and sheen. The placement of Shah Jahan's cenotaph — and his grave — are possibly the only elements of the Taj that do not adhere to perfect geometric proportions and symmetrical precision.

Hades, the god of death and the underworld, is associated with darkness and evil since he is frequently seen as the ancient Greek equivalent of the Christian devil. However, it was not Hades who elected to rule over the underworld. To choose who would rule which kingdom, he and his brothers, Zeus and Poseidon, pulled straws. So, let's just say Hades was unlucky and was sent to the underworld, whilst his brothers, Zeus and Poseidon, were given dominion over the Gods and the sea, respectively. We must remember that, contrary to popular belief, Hades was not the one accountable for either the condemnation or the salvation.

Although Santa Claus is a one-of-a-kind Christmas persona, many actors dress up as the festive figure each year to earn additional money. Mall Santas earn roughly $30 per hour during the holidays, but can earn up to $100 per hour for their services. However, Dan Greenleaf, a professional freelance Santa who owns his own booking agency, told CNBC that the "average hourly mid-range is roughly $150" when he's booked to attend parties, houses, or other events. And if you're very skilled at saying "ho, ho, ho," you might earn $500 per hour. Greenleaf even claims that one of his Santas was promised $1,200 by a Manhattan customer for only one hour on Christmas Day!
