Does your wife work? If yes, may be. If no, forget it.

I am 52 with two kids and I have been doing startups for the last 15 years. You need support from your family and you need good health. It is hard for the family to support you emotionally unless they are financially secured.

"good health"

Thanks for mentioning this. People don't normally think of their health until they lose it. It's so important that I'd represent it like this...

Probability of success = (a + b + c + ... + z) * health

The best advice that I ever received regarding startups is that one needs to think in terms of a three-legged stool, with one leg being our family, one leg being our health and the last one being our career. If two are firm on the ground, we have a fighting chance fixing the third. Otherwise, forget it.
