Ah yes, 20-somethings without kids are famous for having work be their first priority.

Having kids can put a lot more structure into a life that was missing it before. 20-somethings without kids are usually the ones late in in the morning, missing standups, or the ones working while hung over.

I'm sure that it is possible to get someone who is so dedicated to their work that they have no life at any age. Whether or not this is a good idea for your company is a different question.
