After I read this article on Eudaimonia, I have had this urge to read more on the subject. But these days, everything I do, comes associated with a sense of guilt. Hope someday, I'll be able to explore Eudaimonia in more detail. Irony!
Here's a related article which explores Virtue Ethics.
Curiously, there is no mention of (or i couldn't find) Eudaimonia in Russell's History of Western Philosophy. But a chapter on Aristotle's politics mentions that the right age for marriage (in the Hellenic world) is 37 for men and 18 for women :)
