Ask YC: "Can a 40 year old, married with 3 children, start a start-up?"

I have been just watching this site for a few months now. I even bought 'Hackers and Painters', even after reading most of the essays online!

I would like to know what people think of the following two points: 1) Is it best to be young as you tend to have fewer commitments etc? 2) Having little or no money, or being frugal is good. Keeps you focused!

I fail on the first point, but I am a winner on the second!

What do you think? Should I go for it anyway?
