# Why do some people support more electricity than others?

There is a game where people hold by their hands and two of them touch the electrodes of a shock box, then an electric current flows through them. I understand that since they are all making a single path for the current, they create a series circuit, so the current that go through their bodies is exactly the same in every person. On the other hand there is a list of the effects of current through the body:

In the game, some people with very few milliamps say that the electric current that they feel is huge, but others can support quite much. In all cases the current flowing through them is exactly the same, but the pain that they feel is different. Why is this? Is there an special property in their bodies that makes some people support more electricity than others? Is it something more psychological? Do some people have more probabilities to die electrocuted than others?

• There is very little physics to be done when talking about the perception of anything. Even just considering a single person, their perception of the current would be different if they grabbed the electrodes with their fingertips than if they grabbed them by their elbows, etc. – Asher Apr 30 '16 at 17:40
• Whatever you do with electricity, please assume that even $1mA$ can be dangerous. Medical safety standards set the allowed exposure to electricity in the $\mu A$ range. – CuriousOne Apr 30 '16 at 18:02
