Aadhaar is a 12 digit individual identification number issued by the Unique Identification Authority of India on behalf of the Government of India.

The expense ratio is the annual fee that all mutual funds charge their unit holders. This ratio is expressed as a percentage of the fund value. The expense ratio continuously impacts the NAV of a fund. Every day, the published NAV is net of the expense ratio, i.e., the expense is debited from the fund on a daily basis and the NAV is adjusted (decreased) to reflect this debit. It should be noted that by doing it this way, an investor would pay the cost of investing in a fund in proportion to the number of days she is invested in the fund. For instance, if an investor invests in a fund for six months, then the charges incurred will be half the annual expense ratio for the fund - Live Mint

* "in some of the IIMs, more than 95 percent are engineers."

Camels don't store water in their humps; it's actually full of fat! Camels can go up to three weeks without food — using the fat storage as fuel. When the fat is depleted, the bump on their back is no more!

An average person could live for about eight weeks on water alone, give or take about a week for an over- or underweight person, respectively. When the body is deprived of new fuel (i.e., food), it breaks into its energy reserves to keep going. The body stores energy in the form of carbohydrates, fats, and proteins. After one day without food, the body will have used up its carbohydrates, which are stored as glycogen in liver and muscle cells. After that, it's on to the fat reserves. Your average Joe/Jane, weight-wise, has enough fat reserves to live for four to six weeks without food. After that, the body begins to use its protein reserves (basically, the body itself). Body proteins are used up at a much faster rate than fat, and you could really only get another two to three weeks out of protein. At that point, however, you can't really call it living since so much irreparable damage has been done to the body, including the brain - Go Ask Alice!

The constitution of Bhutan specifies that 60% of the country must remain forested

It is a myth that a mother bird abandon her young if touched by a human. Most birds have a poorly developed sense of smell.   One exception: vultures, who sniff out dead animals for dinner.

* In 2009, when I (Nandita Das) was on the Marrakech International Film Festival jury, our president, Abbas Kiarostami, the master filmmaker from Iran, gave a poignant speech at the opening ceremony. In essence he said, “I want to apologise to all the filmmakers whose films we will judge. I recognise the fact that our opinions are subjective and only the films that stand the test of time will be the true winners. But till then, we have been given the uncomfortable task of judging your films. For this, as the jury president, I am sorry.”

* "..responses to any work of art or literature are more often a reflection of one’s own conditioning—perceptions, experiences and exposures" - Nandita Das
