Is your brain replacing itself right now?

Good morning friends,

Here’s something wild-
Nearly every protein in your brain breaks down and rebuilds every few days.

So here’s the question: if your brain is constantly replacing itself, how do memories last a lifetime?

The discovery of “memory glue”
Scientists have identified two molecules that act like glue, keeping your memories intact:

• PKM Zeta – strengthens synapses so memory pathways don’t fade.

• KIBRA – linked to memory performance and brain plasticity, reinforcing the structure of your neural connections.

Without these, memories could simply vanish.
With them, your past stays alive in your mind.

Why this matters
This discovery could transform how we treat Alzheimer’s, amnesia, and cognitive decline-by protecting or enhancing these molecules.

But until therapies are developed, here’s what you can do right now.

How to protect your brain’s memory glue

• Prioritise deep sleep – memory consolidation happens in deep stages; aim for 7–9 hours.

• Boost BDNF – high-intensity exercise and sauna use increase brain-derived neurotrophic factor, strengthening neurons.

• Eat smart – omega-3s from wild fish and choline from eggs enhance synaptic health.

• Keep learning – puzzles, reading, or picking up new skills reinforce plasticity.

The bigger question for you
If your brain is rebuilding every few days-
👉 What habits are you practicing to make sure it rebuilds stronger instead of weaker?
👉 Do you believe lifestyle really has that much power over memory?
👉 And if science finds a way to protect PKM Zeta and KIBRA, would you want to take it?
