Right behind the forehead sits a thin layer of tissue called the prefrontal cortex, thought to be responsible for the executive functions (EF) of the brain:
- self-directed attention
- planning and deciding
- solving problems
- improvising, rehearsing
- handling danger or challenges
- resisting habits or temptations
EF is like a battery, and can be depleted, commonly known as "feeling lazy."
A broken battery is called ADHD, and looks like irresponsible behaviour despite knowing better.
