Thanks for checking it out! I don't think that it's because "[you're] just old"— it's definitely a matter of personal preference, and we know this style of working isn't for everyone.

Re: open offices, that's a good point— I actually think open offices are distracting if people are walking around behind you or chatting in the background. But if everyone else is also hard at work (and therefore not really watching), I definitely feel a small lift from that ambiance/energy.
