Is one data point enough? Col Sanders was 65 when he founded KFC. As I see it, you have solid past experience and secure financial foundations. So the question is really more about motivation. If you still enjoy programming and the selling process a business requires to re-start, then why not? Are there other persons involved? Family or friends who are trying to talk you out of it? Is there something else that you are equally interested in exploring? like traveling the world, starting a different hobby, moving away from SF, etc?
