Our blood has mostly red blood cells (RBCs), white blood cells (WBCs) and plasma. The blood group is determined by these factors. The RBCs have antigens and plasma has antibodies present in it. Antigens can be A or B, and same is the case with antibodies.

This cross between RBCs and the plasma determine our blood group. The antigens are responsible for the blood groups A B AB and O. If antigens have neither A and B, and plasma has either of them then the blood group O is made.

However, in the case of Bombay blood group, the antigen H, which is important for the formation of other blood groups is absent, but it is present in antibody, then the body has no other option but to make it our blood group.

The question arises, how to detect this rare blood group? The blood group is so rare that it is often confused with blood group O, however there are special tests available which makes it easier to diagnose.

The rarest of the rare – Bombay Blood Group Negative

The Bombay blood group negative is rarer than its positive counterpart. There are only 15 negative Bombay blood group donors found in India till now.

The reason why this blood group is mostly only found in Mumbai is said to be the close-community marriages and same lineage interbreeding. This is especially true for some communities in Mumbai.

It is a wonder that the HH blood group is so rare in the world that people can’t find the donors when in need. To make it easier for the people, there is an NGO names Sankalp which connects people who need the blood to the Bombay Blood Group Donors.

The aim of the book is to teach children that families can exist in different forms, and show them how to accept the diversity in family backgrounds.

By Siddhi Jain

Delhi-based author Pritisha Borthakur is set to release her new book, 'Puhor and Niyor's Mural of Family Stories'. The 1,404-word children's book was put together to address a new kind of societal debacle in the family system. The author says the aim is to teach children that families can exist in different forms, and show them how to accept the diversity in family backgrounds.

The author who named the book after her twin sons -- Puhor and Niyor -- is a parent who has seen and heard the tales of ridicule and discrimination suffered by many in India and beyond. She says the book is an artistic illustration for kids that details how different families can live and coexist. Whether it's children with two dads or two moms, children with a single dad or single mom, and even multiracial family units, Borthakur's book teaches love, understanding, and compassion towards unconventional families.

Beyond race, gender, color, and ethnicity which have formed the bases for discrimination since the beginning of time, this book aims to bring to light a largely ignored issue. For so long, single parents have been treated like a taboo without any attempt to understand their situations; no one really cares how or why one's marriage ended but just wants to treat single parents as villains simply for choosing happiness and loving their children.

Homosexual parents, a relatively new family system, is another form that has suffered hate and discrimination for many years. Pritisha emphasizes the need to understand that diversity in people and family is what makes the world beautiful and colourful. 'Puhor and Niyor's Mural of Family Stories' is a firm but compassionate statement against all forms of discrimination on the bases of sexual identity, gender, race, and even differences in background

Clean and maintained hands boost confidence in daily life activities.

If you feel that clean and well-groomed hands are just an essential prerequisite for women, you might like to think twice. Men should equally pay attention to their hands because our hand houses 1,500 bacteria living on each square centimeter of its skin. You can easily assume what havoc it can create in our body because in India we have the culture of eating with our hands and spaces beneath nails can become breeding heaven for germs. Moreover, clean and maintained hands boost confidence in their daily life activities. Therefore, it's important to keep your hands clean irrespective of your gender by washing or sanitizing at regular intervals. And, to keep them groomed, you don't have to visit a salon.

Rajesh U Pandya, Managing Director, KAI India, gives easy and completely doable tips to follow at home:

* Refrain from harsh soaps: You should be mindful of the soap you are using to wash your hands. Your soap can have a moisturizing element in it like aloe vera or shea butter. Ensure that you're washing your hands with normal water as hot water can make your hand's skin dry and scaly.
