Also work life balance/personal runway aspect. It’s a lot easier for a 20 y/o with no significant other, no kids, essentially no bills to work 15 hour days while sharing a small apartment with their cofounder. For younger folks that is new, exciting and an adventure. For the older crowd, well it’s a bit of a tougher sell especially if you have to move from elsewhere into the Bay Area with its astronomical cost of living and you are pulling from savings every month (which already means older folks need savings as a prerequisite for a startup compared to a younger person)

But it works both ways. Having a spouse, kids, obligations can make you hyper focused on providing the best life you can for them.
