Smoking causes significant external damage: premature wrinkles and aging (especially around mouth and eyes), yellowed teeth and fingers, stained nails, gum disease, tooth loss, and psoriasis. These visible effects appear well before internal organ damage.

Smoking constricts blood vessels and reduces oxygen delivery to tissues, which slows wound healing and increases risk of infection and complications after surgery. Quitting before surgery allows your body to recover more effectively and significantly reduces surgical risks.

Children exposed to secondhand smoke have higher rates of respiratory infections, asthma development, and asthma exacerbations due to their developing lungs and smaller airways being more susceptible to smoke irritation.

A single large cigar can contain as much tobacco as an entire pack of cigarettes (approximately 20 cigarettes), and often delivers significantly more nicotine and toxic smoke per session than cigarettes.

American Indians/Alaska Natives have the highest smoking rates in the US, not white non-Hispanics. The question tests knowledge about smoking prevalence patterns across different demographic groups in America.

Smoking reduces bone density and interferes with calcium absorption, significantly increasing the risk of osteoporosis and bone fractures. Smokers have higher rates of bone loss and slower healing after fractures.

Curd (yogurt) is a traditional remedy for dandruff as it contains probiotics and lactic acid that can help balance the scalp's microbiome and reduce fungal growth. While scientific evidence is limited, it's a commonly recommended home remedy.

Hibiscus flowers are widely used in hair oils and traditional hair care preparations. They are believed to nourish hair, prevent premature graying, and improve overall hair quality. The flower is rich in vitamins and amino acids beneficial for hair health.

General relativity incorporates gravity as spacetime curvature, while special relativity (1905) assumes flat spacetime and no gravity. Electromagnetism is in both theories, eclipses were tests, and quantum theory is separate.
