I agree. But in my case I've learned to tolerate pain. I was abused as a child and eventually I would look forward to getting hit because i thought that was how my parents expressed their love. I told myself that I could bear their pain. When I turned 18 my therapist told me that it was wrong. It took me a while to understand. Because I remember my childhood being cheerful but through the lens of an educated adult was actually horrid.
I am a Berserker when I fight, I dissociate then muscle memory and experience do the rest.
