Some people are more tolerant to hot water, it is because their skin is more tolerant of temperature or is it because they are used to it. If so, I my hands in hot water every day. It's hard for me to wash the dishes because I use the cold.

Well, I'm not sure. I always put my hands in hot water and hot water in the shower if I'm hot and it hurts and I do not feel uncomfortable. secondly my grandmother do the dishes in hot water Pure water hot tap or touch and burn me seriously. So I think that tolerance to become more age. Moms also my friend can cook potatoes in the oven microwave, then remove with fingers ouch I Burny Burny. Also some people have a low pain threshold to touch as well.
