Are needs decaying faster after your sim learns magic?

I haven't noticed that much, though the potion of "plentiful needs" is it? Does come in handy with these sims. Finally a way to fulfill the needs of sims without cheats! And umm.. I did notice that if sims spend lots of time practicing magic, then that can give that illusion since time seems to fly, and the sages I've noticed their needs don't seem to decay. Not sure if anyone else noticed that though!
