We have all seen AI-based searches available on the web like Copilot, Perplexity, DuckAssist etc, which scour the web for information, present them in a summarized form, and also cite sources in support of the summary.

But how do they know which sources are legitimate and which are simple BS ? Do they exercise judgement while crawling, or do they have some kind of filter list around the “trustworthyness” of various web sources ?

    I regularly ask it these questions and have yet to have it too far off of what I’d find from people on any forum.

    Here is me asking it today

    A heart rate of 178 BPM (beats per minute) can be healthy depending on the context:

    ✅ Healthy in Certain Situations:

    If you’re exercising intensely, such as during cardio workouts, running, or high-intensity interval training (HIIT), 178 BPM can be normal and expected, especially if:

    You’re younger (e.g., teens or 20s)

    You’re fit and accustomed to high heart rate workouts

    General formula for max heart rate:

    220 - your age = estimated maximum heart rate So for a 25-year-old: 220 - 25 = 195 BPM max 178 BPM would be about 91% of max, which is high, but acceptable during vigorous effort.

    ⚠️ Not Healthy at Rest:

    If your heart rate is 178 BPM while resting, sitting, or sleeping, that’s too high and could be a sign of:

    Tachycardia (abnormally fast heart rate)

    Anxiety or panic attack

    Dehydration

    Fever

    Heart condition or arrhythmia

    Stimulant or drug effects (e.g., caffeine, medications)

    📌 Summary:

    Situation 178 BPM

    During intense exercise ✅ Normal At rest or light activity ❌ Needs medical attention

    If you’re unsure or it feels abnormal, it’s always safest to consult a doctor.
