Generally speaking, HRV is one of the hardest metrics to improve, especially when you're already at a mid-to-high level—pushing it further basically requires serious effort. But over the past two months, I've seen a consistent month-over-month increase of +14%, with my average HRV hitting 77 last week (and that's with two days of drinking—those who know, know, alcohol is devastating for HRV). I did one thing: I structured all my test reports—blood metrics, ultrasound, color Doppler, health check data, supplement list—and fed them into AI, asking it to redesign my supplementation plan based on real data. The result? It cut out a bunch of unnecessary stuff and added some supplements that truly targeted my metrics. After two months of following the plan, my HRV gave immediate feedback. What's even more interesting is that I didn't even use any "medical-specific large models," just ChatGPT and Gemini. Comparing the two, I lean more towards the former—it’s more logical, provides detailed explanations, and has a clearer reasoning chain. Honestly, the results even shocked me. It's not just a "feeling better" kind of thing—it’s an improvement at the data level. If AI can optimize individual health to this extent, humanity pushing average lifespans to 100 years is really not science fiction.
