This might be a bit OT but still interesting. Most mammals brains are designed to appropriately deal with threats. You know - fight, flight or freeze. For most mammals this works and it did for us too.

But today we rarely are in situations that need these strategies. We have more complex problems that we need to respond to.

So we tend to overreact to things that aren’t really dangerous, like talking in front of people or going on a date. And at the same time under reacting to dangers like the climate crises or other dangers that lie far in the future, like if you don’t quit smoking you will get sick. We can’t really deal with abstract fears in a relevant manner.
