Short answers to the big questions.

How accurate are smartwatch ECGs?

Reasonably good at flagging obvious atrial fibrillation, but never a substitute for a clinical ECG. Use them as a screener, not a diagnosis.

When should I start HPV screening?

From age 25, every 3–5 years, depending on your last result. After 30 we recommend co-testing with HPV DNA every 5 years.

Is burnout different from depression?

Yes — distinct syndromes, though they often overlap. Burnout is work-specific; depression is pervasive.

Can type 2 diabetes really be reversed?

Early-stage cases, yes — with structured intervention within the first 2 years. Long-standing cases can achieve remission but rarely full reversal.

Do I really need a colonoscopy at 45?

Yes — most international guidelines now recommend from 45, earlier with family history. It's a one-day commitment that prevents a life-changing diagnosis.

Is my child's fever dangerous?

Generally no. Fever is a sign the immune system is working. Watch for duration, hydration, and behaviour, not the number on the thermometer.
