The International Day against Drug Abuse and Illicit Trafficking is observed on June 26th annually. It was established by the United Nations in 1987 to raise awareness about the global drug problem.

This is a Tamil lyric or poetry completion. The phrase translates to a poetic expression, and 'isayil thodangudhamma' (shall I start in music/song) is the correct continuation. This appears to be from Tamil literary or musical tradition.

New Delhi is the capital of India, located in the National Capital Territory of Delhi. It houses all major government institutions including the Parliament, Rashtrapati Bhavan, and the Prime Minister's office.

The average height difference between men and women is approximately 5 inches (about 13 cm), not 10 inches. Global averages are roughly 5'9" for men and 5'4" for women. The 10-inch figure is an exaggeration of the actual sexual dimorphism in human height.

Dream frequency and recall are not correlated with intelligence. Scientific research shows that all humans dream during REM sleep, regardless of IQ level. This is a common myth without scientific basis - dreaming is a universal neurological phenomenon.

Walking actually engages approximately 200 muscles, including muscles in the legs, core, back, and arms for balance and coordination. The 50-muscle figure is a significant underestimate. Human gait requires coordinated effort from muscle groups throughout the body.

There is no consistent anatomical relationship between thumb length and nose length across humans. Body proportions vary significantly between individuals, making this comparison meaningless. This is a classic urban legend with no scientific validity.

Tooth development (odontogenesis) actually begins during fetal development, well before birth. Primary teeth start forming around 6-8 weeks in utero, though they typically erupt months after birth. The statement is inaccurate because development starts prenatally.

Human skin hosts millions of bacteria per square inch, so each foot would have billions, not thousands. The skin microbiome is incredibly dense, with estimates of 1 million to 1 billion bacteria per square centimeter. One thousand bacteria is a vast underestimate.

While gastric acid (hydrochloric acid, pH 1.5-3.5) is extremely corrosive and can dissolve organic materials and some metals, completely dissolving a stainless steel razor blade would take extended time. The statement oversimplifies - acid can corrode and eventually damage metals, but instant dissolution is exaggerated.

The statement is false. While the human brain as a whole contains enormous information capacity estimated at terabytes, individual brain cells (neurons) cannot hold more information than the Encyclopedia Britannica. A single neuron stores far less information than the entire encyclopedia.

The statement is false. Food travels from the mouth to the stomach through the esophagus in approximately 6-8 seconds via peristalsis (wave-like muscle contractions), not 2 minutes. The 2-minute figure is incorrect for the swallowing process.

The statement is false. Dreams typically last much longer than 2-3 seconds. During REM (Rapid Eye Movement) sleep, which is when most vivid dreaming occurs, dreams can last from 20-30 minutes. The 2-3 second figure is incorrect.

The statement is false. The average human body at rest produces about 100 watts of heat energy. In 30 minutes, this equals roughly 180,000 joules, which is insufficient to boil half a gallon (about 1.9 liters) of water from room temperature. Boiling that amount of water would require significantly more energy.
