Ask HN: How does marriage affect the creation of a (successful) startup?

Paul Graham said in his essay "How to start a startup" that the best age to start a startup is between 23 and 38. Among these people, some of them must be married, right? So I have been wondering how a married life (and possibly one with kids, ugh) affect the chances and the process of creating and running a startup. Now, assuming that marriage is supposed to be a very important part of life, I imagine that it is rather hellish because Paul Graham also said that "Startups Take Over Your Life".

How does a married hacker do it?

I am 28, I just got married in May and I am pondering the possibility of starting something with my hacker friends in Hong Kong.

Would any married startup founder enlighten me (and other prospective married hackers)?
