because we have been using them for years. They seep inside your skin.
My telephone extension at work is 741 - now how many of you know what one of those are - been using them for 40 years.

Fyi - this place sells a board with 4 relays that you can connect directly to an Arduino output pins.  It is not a "shield" that mounts on the arduino but comes with wires for each relay that are easy to connect to whatever arduino board you have. Also you have to provide a separate 12V supply to the relay board to activate the relays. Here is the link: http://www.pimpmyprop.com/RB4RelayBoardDetails.htm.
