所以，程序员们，为什么不做一个APP把HowToliveLonger的执行情况记录下来呢

只要执行的人多，就有分析数据了。
所以，是不是要请 @geekan 先设计好实验/实践的模型呢？

The issue proposes an app to record how people follow HowToLiveLonger and analyze the resulting data, but names no files, tests, or entry points. Start by reviewing the repository and discussing the experiment or practice model with the maintainer. Done would require an agreed scope, data model, and implementation plan, none of which the issue currently defines.
