About HealthyLifeHub

Who writes here

My name is Kkuma Park. I’m an independent writer and developer based in Seoul, South Korea. I’ve spent more than a decade in IT, built a handful of small software products, and along the way accumulated a list of personal experiments, mistakes, and hard-won notes that turned into this blog.

I burned out hard at 29 — couldn’t sleep, gained 15kg, ignored every warning sign. HealthyLifeHub is the playbook I built over three years of slow, measurable changes that actually stuck. I log my own bloodwork and sleep data, not just hype.

What HealthyLifeHub is for

HealthyLifeHub is my working notebook on health and wellness. Every article here exists because I needed the answer myself at some point and couldn’t find a version I trusted.

I try to follow three rules on this site:

1. Write from experience, not summary. If I haven’t actually done it, I won’t pretend I have.
2. Show the numbers. Where real data, tests, or costs are useful, I include them.
3. Update when I’m wrong. If I learn that an earlier post was inaccurate, I fix the post and add a note.

How I run this blog

• Posts are published on a regular schedule.
• I use AI tools (such as ChatGPT) to help with drafting structure and outlines, but every published post is reviewed, edited, and fact-checked by me before it goes live.
• Affiliate links, when used, are marked. I only link to products I have actually used or would genuinely recommend.
• Ads on this site come from Google AdSense once my site is approved. Ads help keep the site free to read.
