If:

* the pay is great

* work/life balance is sane

* the CEO/your direct manager has a family/children

then of course.

> the CEO/your direct manager has a family/children

Why would that matter?

Not the poster, but I assume the idea is because a company of only young people often don't consider or understand the limitations/responsibilities of family life. Once you have kids, suddenly "corporate weekend trips!" and "hackathon all-nighters!" and even "beers after work on Friday!" become complicated commitments that require adjustments from the whole family. With a couple family-havers in the mix there is usually more acceptance of the work-life divide, or even that one exists (or should).

Because he goes home at night and has stuff to do thats not work and he isnt jealous of you for having that. Worst managers I ever worked for are divorced (and to an extent single) and hate seeing happily married employees

One of those 3 things is different to the others

i don't judge people by their age -- i've had absolutely amazing young coworkers and crazy shitty older ones (and the other way around).

i would 100% work at a place with younger people AND at a place with older people. it all depends on how the company's culture handled all this.

(and why you are interviewing the company as much as the company is interviewing you).

The ideal thing is a mix that is somewhat representative of the population at large. It's good to have different perspectives and attitudes and experience. Sometimes lack of experience to question 'why we do it that way', but it's also usually good to have someone who knows that we do it that way not "because", but because doing it another way can lead to subtle problems that are hard to diagnose.
