Physical pain (physical process, objective) causes us suffering (a subjective experience). Too much suffering caused by pain causes the brain to fail and cause fainting or even death.

Suppose that in the future the human body will become much more resistant, but also with many more nerves that, theoretically, can transmit much more information to the brain.

In this case:

1. The changes will take place only on a physical level, but the suffering, as a subjective perception, will be practically the same.

2. Due to the increase in endurance, the brain will give in much harder, leaving suffering much more room for maneuver until fainting or death, and the perceived torment will be proportionally greater than at present.

Which one is correct?
