Life Ledger Calculator

See today's lifestyle signal in life-hours. 把今天的生活信号，换算成生命小时。

Enter rough daily signals. The estimate stays in your browser, uses population-level research curves, and is not medical advice. 输入粗略日常数据。估算只在浏览器内完成，基于群体研究曲线，不构成医疗建议。

Population evidence

Curves come from Entropy's existing epidemiological source table, including BMJ, AHA, JAMA, Lancet, and Frontiers references already used by the app engine.

Wide uncertainty

Single-day inputs are noisy. The result shows a broad range and should be treated as a conversation starter, not a precise biological measurement.

Seven days matter

The full Entropy experiment is a 7-day ledger because patterns are more useful than a single isolated day.
