"At 25, your frontal lobe is developed and your brain is done cooking"
Literally makes me want to rip my hair out. People use this as a way to justify any stupid behavior committed before you turn 25, and not only that, people think you suddenly turn into a wise sensei at 25 and you just wake up one day and everything feels different.
People need to realize the brain is constantly changing, and people need to stop throwing this myth around as a fact. It leads to infantilization
