Your energy and willingness to learn mean quite a bit; your calendar age does not. A 20 year old with a couple kids, a wife to go home to, a mortgage and a ton of student loan debt might have serious concerns about the startup life.... while a 40 year old single woman with no dependents might find it suits her well. Will startup life take a lot of your time and energy? Absolutely yes. But if you have that energy to give, then you're good. Just try not to be to starry eyed: The company is probably going to fail, you're probably going to be overworked and underpaid, and you'll probably get in more than a couple fights with your coworkers. But some people (like me) love that kinda stuff. Whatever works for you.
