There are a lot of theories about how old you "should" be to found a startup.
Some people say younger is better. You're young and strong and can withstand lots of sleep deprivation and keep going. You're more likely to take risks and less likely to quit (supposedly).
On the other hand, wisdom comes with age. The older you are, the better you know your industry, and likely more than one industry. You have strong connections and a lot of experience.
