London - The traits and tendencies you can blame on your genes.
Research shows people differ widely in their sensitivity to pain - some can easily withstand sensations that others would consider unbearable.
At the opposite end of the spectrum there are those who feel pain much more acutely than average.
This could be linked to the COMT gene. Scientists have found three variants attached to this gene, which are linked to low, average and high pain sensitivity - meaning your pain threshold could have been passed down in your family. How much we feel the cold or heat also appears to be partly determined by genetic make-up.
Geneticists at California’s Genomics Institute of the Novartis Research Foundation have identified some of the genes that make the skin respond to cold or warm temperatures.
It’s likely that some people are genetically encoded with more sensors for either hot or cold, explaining this variation in sensitivity. - Daily Mail
