You’re not a double adult at 36 🙂 You became a full adult 10 years ago. Now you’re just an older, slightly slower adult and it’s gonna get worse exponentially fast.
What makes 26 a full adult?
The brain reaches full maturity around 25. Some parts of the brain stop developing long before then but the pre-frontal cortex is an exceptionally slow developer. It’s responsible for cognitive control: self-regulation both internally and externally.
Basically if you don’t learn behavioural regulation by the age of 25, it’s going to be harder to unlearn those habits afterwards. This is often seen in people who constantly make poor life choices and don’t seem to be able to stop, or people with poor emotional control.
Now’s a good time to build all of your musculature, strong bones, to help you live the rest of your life with high quality strength and ease
Should I double my muscles and bones? Stem cell injections?
