Our findings show the importance of looking at objective as well as subjective measurements of how the body responds to pain stimuli.

The findings from both studies indicate that the effect of exercise we found in the current study truly represents an enhanced rate of wound healing in older adults.

This kind of evaluation is in some ways a more objective way of measuring the body's response to pain, as opposed to simply asking someone if they feel pain.

For subjective indicators of pain, obese people indicated similar levels of pain to non-obese people. But when we looked at objective indicators, we found that the obese group had a lower threshold for pain.

Subjective artists are one-eyed, but objective artists are blind.

Perception is subjective.
