In this concise YouTube short, the presenter explains that the human brain possesses a built‑in negativity bias, a defensive wiring that makes us focus on potential threats rather than possibilities. She cites a statistic that the average person generates around 60,000 thoughts each day, with roughly 80 % of those thoughts being negative unless the brain is actively trained. The speaker frames this as a call to develop "mental fitness"—deliberate mental training that can override the default bias and promote more balanced, positive thinking.

Did you know that the average human brain processes 60,000 thoughts per day, but 80% of them are negative unless they're actively trained? So you see how important mental fitness is?
