About 1 billion. That's how many heartbeats almost anything gets in a lifetime. A mouse spends them in two years. An elephant stretches them across 70. Same total, completely different pace.
Every heartbeat is a withdrawal from a fixed account. No bonuses, no extensions. Once you start spending, the counter only goes one way. Your heart fires roughly once per second. 86,000 beats a day. Over 30 million a year. Quiet math. Ruthless outcome.
Small animals don't die young by accident. Their hearts sprint from birth. Big animals idle. Some whales beat so slowly it feels like time pauses between them. Evolution didn't count birthdays. It counted beats.
You don't age because time passes. You age because your heart keeps moving. Nothing truly gives you more heartbeats. All we ever change is how fast we burn through them. Life isn't short. It's just spent quickly.
