People often cry when they are mad because anger triggers intense emotional and physiological stress, and crying is one of the body’s built-in ways to release that overload. When anger becomes overwhelming-especially if it is mixed with hurt, frustration, or helplessness-the nervous system can tip into a state where tears are a natural outlet, not a conscious choice. Crying during anger does not mean someone is weak, overreacting, or confused about how they feel. It usually means the emotional system is overloaded and responding automatically. ...

People get déjà vu because the brain briefly misfires in how it processes familiarity and memory. In simple terms, the brain mistakenly signals that a current experience is familiar-even though it is actually new. This creates the strong, often unsettling feeling that “this has happened before,” despite knowing logically that it has not. Most researchers agree that déjà vu is not a memory of the past and not a sign of prediction or supernatural awareness. It is a short-lived cognitive glitch involving perception, memory recognition, and timing within the brain. ...

People grind their teeth in their sleep-known medically as sleep bruxism-primarily because the brain is reacting to stress, disrupted sleep, or misaligned signals between the jaw muscles and the nervous system. It is not a conscious habit. It happens involuntarily, often during light stages of sleep or brief awakenings that the person does not remember. In simple terms: the body is tense or overstimulated at night, and the jaw muscles express that tension by clenching or grinding. While dental alignment can play a role, stress and sleep-related factors are the most consistent drivers, not “bad teeth” alone. ...

Many people dislike Colleen Hoover because they feel her books romanticize unhealthy relationships, oversimplify trauma, and rely on repetitive emotional tropes, despite being extremely popular. The criticism is less about her success and more about how her stories handle sensitive themes like abuse, consent, and mental health. At the same time, millions of readers genuinely connect with her work. The backlash exists because her popularity is massive, her themes are emotionally charged, and expectations for responsibility rise when an author reaches that level of influence. ...

People smoke cigars primarily for enjoyment, ritual, and social signaling-not because they are addicted in the same way cigarette smokers often are. For most cigar smokers, the appeal lies in taste, relaxation, tradition, and the experience itself rather than nicotine delivery. Unlike cigarettes, cigars are typically smoked occasionally and slowly. Many smokers do not inhale; they focus on flavor, aroma, and the act of smoking as a deliberate leisure activity. In short, cigars are less about dependency and more about experience, identity, and context. ...

People take creatine primarily to improve physical performance-especially strength, power, and muscle recovery-and, in some cases, to support brain energy and cognitive function. It helps the body produce quick energy during short, intense activities like weightlifting, sprinting, or high-intensity sports. For most users, creatine is not a steroid, not a hormone, and not a shortcut to muscle growth. It is a naturally occurring compound already found in the body and in foods like meat and fish. Supplementing simply increases the available supply. ...

People take ivermectin primarily because it is an effective, approved medication for treating certain parasitic infections in humans. It has been used safely for decades to treat conditions such as river blindness (onchocerciasis), strongyloidiasis (a type of intestinal worm), and scabies. More recently, some people have taken ivermectin for unapproved or unsupported reasons, most notably during the COVID-19 pandemic, when it was promoted online as a preventive or cure despite a lack of reliable evidence supporting that use. ...

We adjust coefficients-the numbers placed in front of chemical formulas-when balancing chemical equations because coefficients change the quantity of molecules, not the identity of the substances. We do not adjust subscripts because subscripts define the chemical structure and identity of a compound. Changing a subscript would mean creating a different substance, which violates the reality of the reaction. In short: Coefficients = how many molecules participate Subscripts = what the molecule actually is Balancing equations is about conserving atoms, not redefining molecules. ...

We celebrate Lohri to mark the end of winter and the arrival of longer days, especially in northern India. At its core, Lohri is a harvest and seasonal festival. It expresses gratitude for nature’s cycles, celebrates agricultural abundance, and honors community, warmth, and renewal. The festival is closely associated with Punjab, Haryana, Himachal Pradesh, and parts of North India, and is traditionally linked to the rabi crop season, particularly wheat. The bonfire at the center of Lohri symbolizes the sun’s return, warmth, and life after cold months. ...

People eat khichdi on Makar Sankranti because it is traditionally believed to provide warmth, balance, and nourishment during the seasonal shift that occurs around this festival. The dish-made from rice and lentils, often with ghee and mild spices-aligns closely with Ayurvedic dietary principles for winter-to-spring transition. Over time, this practical food choice became a ritualized cultural practice, especially in parts of North and Central India. In short: khichdi is eaten not for symbolism alone, but because it suits the body’s needs during this time of year, and that practicality evolved into tradition. ...

We have belly buttons because they are the scar left behind after the umbilical cord is cut at birth. Before birth, the umbilical cord connects a developing fetus to the placenta. Through this cord, oxygen, nutrients, and waste products are exchanged between the mother and the fetus. After birth, the cord is no longer needed and is clamped and cut. When the remaining stump dries and falls off, it leaves a small scar on the abdomen - what we commonly call the belly button, or navel. ...

We need political parties because modern democracies cannot function without organized groups that represent ideas, interests, and people. Political parties help citizens choose their leaders, form governments, make laws, and hold power accountable. Without political parties, democracy would become chaotic, inefficient, and largely unworkable-especially in large countries like India. At the Class 10 level, the core idea is simple: political parties make democracy practical. They connect ordinary people to the government by organizing opinions, contesting elections, and running the administration once elected. ...

We sneeze when we’re sick because the body is trying to clear irritants, viruses, mucus, and inflammatory chemicals from the nasal passages. Illness-especially colds, flu, COVID-19, and sinus infections-irritates the lining of the nose. That irritation overstimulates nerve endings, which triggers a sneeze reflex designed to expel the problem forcefully. In simple terms: sneezing is a defensive reflex, not a symptom by itself. When you’re sick, the nose becomes inflamed, congested, and chemically active, making that reflex easier to trigger and harder to suppress. ...

People wear black on Makar Sankranti mainly for practical, seasonal reasons, not religious ones. Black absorbs and retains heat, which helps keep the body warm during mid-January-one of the coldest periods in many parts of India. Over time, this practical habit became a widely followed cultural custom, especially in regions like Maharashtra. There is no religious mandate in Hindu scriptures that requires wearing black on Makar Sankranti. The practice is rooted in climate, comfort, and local tradition rather than theology. ...

Makar Sankranti is celebrated to mark the sun’s transition into the zodiac sign Makara (Capricorn), an astronomical event that signals the end of winter and the beginning of longer, warmer days in the Northern Hemisphere. Unlike many Hindu festivals that follow lunar calendars, Makar Sankranti is based on the solar calendar, which is why it falls on nearly the same date every year, usually January 14 or 15. At its core, the festival represents renewal, hope, and gratitude-especially gratitude for the harvest and for the sun, which is seen as the source of life, energy, and prosperity. ...
