You got about 10 years to make to make up your mind. I asked Google AI "When does a male human's brain gel?" and here is what it said:
It appears you're using "gel" as a metaphorical term for reaching maturity or completing development.
Based on current research, the male human brain doesn't fully develop, in terms of reaching complete maturity and efficiency in all areas, until around 25 years of age, or even as late as 30.
Specifically, the prefrontal cortex, responsible for executive functions like decision-making, planning, and impulse control, is one of the last areas to fully mature. While the brain undergoes significant growth and forms numerous neural connections in early childhood, the process of myelination (insulation of nerve fibers for faster transmission) and synaptic pruning (elimination of unused connections for efficiency) continues well into adolescence and early adulthood.
It's important to remember that brain development is a complex and ongoing process influenced by a variety of factors, including genetics, environment, experiences, and lifestyle choices.
My brain gelled at age 26.
