No, I was saying that it causes aging physically, but since we do not see their ghosts, any corruption from the dark side won't be known to us since they died as evil men. Dooku doesn't use the dark side to prolong his life and we know that Maul did, but we don't see what happened beyond the last time he was seen. Anakin wasn't evil. He did make a mistake, but it is the kind of mistake any one of us could make. That doesn't make us evil, unless you believe any form of murder is wrong.
