      Hey Sean,
      I don’t know, that’s a strange one! Maybe it’s because you might be wearing shoes with rubber soles when other people aren’t?

      Hi Sean,

      when you touch the electric fence the current wants to flow through you. If you stand on the ground you provide a pathway for the current to flow, as it wants to go to ground and so the passage of the (low strength) current gives you a small shock.
      If you wear shoes made from insulating materials, such as rubber soles, then the current cannot go to ground and you feel no shock. So birds can site on the electric wires and be fine as they never touch the ground.

      There may also be individual factors that determine if the current will flow through you or not, but that is outside my area.

      One should really test the different people under the same conditions to look at this properly. I would think being sweaty for example may allow current to flow compared to someone who is not perspiring.

      but nice question!
