What's Your Heart Rate?

from Google AI:

A normal resting heart rate for healthy adults ranges from 60 to 100 beats per minute (bpm) while calm and inactive. [1]

Key Resting Heart Rate Guidelines

Standard Adult Range: 60–100 bpm
Athletic / Fit Range: 40–60 bpm (or lower, down to around 37–38 bpm in ultra-trained athletes) is common and usually healthy
Bradycardia: A resting heart rate consistently below 60 bpm (concerning if accompanied by dizziness, fatigue, or fainting)
Tachycardia: A resting heart rate consistently above 100 bpm [1, 2, 3]

An average human heart beats about 35 million to 37 million times in a year. [1, 2]

The Breakdown
Per day: Approximately 100,000 beats (based on an average resting rate of 60 to 100 beats per minute).
Per year: Roughly 35 million to 36.8 million beats.
Per lifetime: About 2.5 billion to 3 billion beats over a 70- to 80-year lifespan according to health insights from the Cleveland Clinic Health Essentials. [1, 2, 3, 4, 5]
Note: The exact number changes depending on your individual heart rate, age, fitness level, and how much time you spend resting or exercising
