I must make one point.
Lightsabers do not cause bleeding. They are so incredibly hot that they carterize the wound as soon as it is made. Just go watch any of the Star Wars movies and you will see that when a limb is cut off there isn't any blood.
SOrry wrong. May I refer you to Star Wars Episode IV : A new hope. When Obi-wan cut off the aliens arm in the bar there was a pool of blood.
