This makes sense. Evolutionarily speaking, if I was stressed about nearly escaping a lion or tiger during my adolescence, it is going to serve me well to remember this and return to this stressor / practice this response later on.

Like with many things, our brains are wired to respond to stimuli in a way that would have benefitted us hundreds of thousands of years ago. Our brains are not at all wired for our modern world.
