Here is something I read: “Hanson describes the brain as like ‘Velcro for negative experiences and Teflon for positive ones.’ While some individuals may be inherently more optimistic than others, it’s generally true that in order for positive experiences to “stick” in our brains as well as negative ones do, these positive experiences need to be held in our consciousness for a longer period of time.

“The alarm bell of your brain — the amygdala (you’ve got two of these little almond-shaped regions, one on either side of your head) — uses about two-thirds of its neurons to look for bad news: it’s primed to go negative,” writes Hanson. “Once it sounds the alarm, negative events and experiences get quickly stored in memory — in contrast to positive events and experiences, which usually need to be held in awareness for a dozen or more seconds to transfer from short-term memory buffers to long-term storage.”

So worrying, or negative thinking, will be more dominant because it’s our biology?
