Ask HN: People above 35, would you risk your job and start a company?

Hi, We've all heard the stories of whatsapp founders. I wanted to know if it's more of an exception than a rule. Assume you have a brilliant idea and you have the capability to execute it, would you risk your day job to start your company ? Are there any examples here , above 35, who've started a company successfully ?

By successful, I mean, you earn decent enough income to live just as good or better than what you did on a day job.
