Fenrix shrugged. "I do not know, I know that people, and elves.. can feel sick or tired although it is usually tired, from casting spells" he scratched his chin. "But that is mostly from casting too many spells at once and too many in short periods of time, you on the other hand..." he trailed off. "Oh right, you on the other hand don't seem to have much will power, meaning you do not have allot of magical energy... strange..." he sighed. "It is apparent in humans allot of the time, but never in elves..." he sighed fiercely.
