It's the same concept as 'Achille's heel', a Greek mythology concept about a single vulnerability, which all beings have, even seemingly strong and all-powerful ones.
It could be in your mind, your relationship, or any other part of life.




On a physical level, I cannot handle thrill rides, adventure sports, and spicy food. I stay away from all of that stuff. It's not fun for me, it's unpleasant-stressful.
On a psychological level, it might be hyperactive people who can't sit still, and even all conversation with them bounces around frantically so that you can never get in-depth with anything with them. I'm the complete opposite. Calm physically, and I like to go deep when I do learn about or talk about things. Surface, shallow stuff drives me bonkers if that's all there is. Levity and playfulness is great in between depth, but I need both. I can't be around people with no attention span or focus.
