Today Is Nail Technician Day, a professional holiday for nail care specialists. Nail care has deep historical roots: in ancient Egypt, nail color indicated social status—slaves wore pale shades, while the elite favored bright hues (Cleopatra, for example, preferred terracotta). In ancient China, long nails symbolized wealth and freedom from manual labor. According to expert estimates and industry data, Russia is home to around 350,000 nail technicians, with the Russian manicure and pedicure market projected to exceed 230 billion rubles by 2026.

World Depression Awareness Day is observed annually on March 24. The day aims to draw public attention to one of the most serious modern challenges—depression as a genuine mental illness, not just a "bad mood." Typically, depression involves prolonged feelings of sadness, loss of interest in life and daily activities, fatigue, low energy, and sleep disturbances. The World Health Organization reports that over 350 million people worldwide suffer from depression. Women—especially postpartum—teenagers, and those experiencing stress, loss, or chronic illness are at higher risk. Mental health is just as vital as physical health, and depression is treatable. The first step toward recovery is recognizing the need for support.

Who are phthisiatrists? They are physicians specializing in the study of tuberculosis—its causes, diagnosis (regardless of the affected organ: lungs, liver, intestines, bones, skin, etc.), and treatment and prevention. The disease was once called "consumption," derived from the word "to waste away." Until the mid-20th century, it was largely incurable. Notably, the date for Phthisiatrist Day was chosen to mark a historic event: on March 24, 1882, German microbiologist Robert Koch announced his discovery of the tuberculosis pathogen. Commonly known as the "Koch bacillus" after its discoverer, this breakthrough earned Koch the 1905 Nobel Prize in Physiology or Medicine. Today is also World Tuberculosis Day, symbolized by the white daisy, representing healthy breathing.
