Start Here
New here? Here’s where to start.
Simply Younger has 70+ posts across four different topics. Rather than leave you to pick randomly, here’s the short tour.
The one thing everyone should do first
Before you read a single blog post, do this: take the free Hydration Quiz. It’s a three-minute assessment I built because hydration is the area where almost everyone has the biggest blind spots and the fastest potential wins. You’ll get a personalised score and a few practical next steps based on your actual answers — not generic advice.
Why start there? Because most of the other stuff on this site — training, sleep, recovery, mindset — gets significantly harder if your cellular hydration is quietly broken. Fixing the foundation first tends to make everything else work better.
Then pick your lane
Simply Younger content sits in four lanes. You probably came here for one of them. Here’s where to start inside each.
If you’re here for the hydration science
Start with The Hydration Paradox — the post that explains why drinking more water often doesn’t help. Then read What’s Actually In Your Tap Water for the contaminant side. Then Hydrogen, Structure, and Light if you want to go deeper into functional water science.

If you want to train and perform better after 40
Start with The Science of Building Muscle After 40 for the training framework. Then read Why I’ve Worn WHOOP for 792 Days Straight for the measurement side. Then The Power of Daily Movement for the non-negotiable that holds everything together.

If you want the mental side
Start with You Don’t Need Motivation. You Need Standards. That post is the closest thing to a thesis statement for how I approach all of this. Then read The Comfort Trap Nobody Talks About and You Don’t Rise to the Level of Your Goals — You Fall to the Level of Your Systems.

If you just want to follow along
The Journal is the real-time log — fasting updates, weekly check-ins, book notes, and the messy human side of running an experiment on yourself. Start with whatever’s at the top. That’s the whole point of the Journal.

One last thing
If the hydration stuff resonates and you want to go deeper with a group of people who care about getting this right, I also run a private Facebook community called Code of Hydration. It’s education-first, the conversations are actually good, and there’s no pitch at the end of any of it.
Welcome. Take what’s useful. Ignore what isn’t.
