If that is all you are saying now then I agree with you. Earlier you were saying that "Running isn't boring" which is a very different statement. I don't find running as boring as some do, but I find the notion that you cannot be bored while in pain to be quite alien. If you work that way then fine, but neither I nor anyone I know who has been stuck doing something boring while in pain has had the same result as you.
I don't think we're in agreement. You can't be bored and be in pain at the same time. You're either bored, or you're in pain, you can't be bored while getting punched in the face or running 100 miles.
Your statement "You can't be bored and be in pain at the same time" is utterly ridiculous. According to Google, bored means "feeling weary because one is unoccupied or lacks interest in one's current activity". Pain does not hold my interest so it does not prevent me from lacking interest in my current activity.
Different people respond to pain differently. You are allowed to be different and given the small sample size available to me it is even possible that people like you are common. What I find annoying is you inability or unwillingness to understand that not everyone is you. Or perhaps you just don't know what "bored" means.
