ading means slowing down and paying attention to exactly what a text says and how it says it: word choice, images, sentence rhythm, repetition and what is left unsaid. Start with a short passage and annotate it, circling striking words and noting your questions and reactions in the margin. Then ask why the writer made those choices and what effect they have on you. A useful claim about literature points to specific evidence from the text and explains it, rather than simply summarising the plot. Close reading is a skill you can carry anywhere, from a sonnet to a song lyric to a political speech." } ] }, { "id": "medicine", "name": "Medicine & Health", "host": "fren", "blurb": "How the body works, how it fails and how to keep people well.

Anatomy studies the structures; physiology studies how they work. A central idea in physiology is homeostasis, the body's ability to keep internal conditions such as temperature, blood sugar and blood pressure within narrow ranges. Most of this control works through negative feedback: when body temperature rises, sensors detect it and the body responds by sweating and widening skin blood vessels until temperature falls back. Many diseases can be understood as homeostasis breaking down." }, { "id": "health101", "title": "Public Health and Prevention", "host": "fren", "desc": "Health for whole populations: epidemiology, vaccines, clean water, nutrition and evidence-based prevention.", "lessons": ["What is public health?", "Epidemiology: counting disease", "Vaccines and herd immunity", "Water, food and sanitation", "Lifestyle and chronic disease"], "intro": "Medicine usually treats one patient at a time; public health aims to keep entire populations healthy and to prevent disease before it starts. Some of its biggest wins look ordinary: clean drinking water, sewage systems, vaccination programmes, safer food, seat belts and smoke-free laws have saved enormous numbers of lives. Public health relies on epidemiology, the study of how diseases are distributed in populations and what causes them, using measures such as incidence (new cases over a period) and prevalence (all current cases). Throughout this course, remember that this is general education; for any personal health question, talk to a qualified health professional." }, { "id": "mind101", "title": "Mental Health and Wellbeing", "host": "fren", "desc": "Stress, sleep, mood and resilience: what science says about looking after your mind, and when to seek help.", "lessons": ["What is mental health?", "Stress and the body", "Sleep", "Mood, anxiety and depression", "Habits that help", "Getting support"], "intro": "The World Health Organization describes mental health as a state of wellbeing in which a person can cope with the normal stresses of life, work productively and contribute to their community; it is more than the absence of illness. Mental health sits on a spectrum and changes over time, just like physical health. Stress is a normal response that helps us meet challenges, but long-lasting stress can harm sleep, mood and the body. Basic habits such as regular sleep, physical activity, time outdoors and real connection with other people support wellbeing. If you or someone you know is struggling or in danger, reach out to a trusted person, a doctor or a local crisis line right away." }, { "id": "first101", "title": "First Aid Basics", "host": "hello", "desc": "What to do first in an emergency: check for danger, call for help, CPR awareness, bleeding and burns.
