I've been a remote engineer for about 10 years now, just over 50, enjoy programming but most of my friends have dropped off or gone crazy (trumpers) in recent years, and I never got married.

Side note, inviting views from both sexes makes for some very interesting short conversations. Both have very very different takes on the same things and therefore won't talk too long. Both being interested in very different things (think dress belts, hair supplements, birth control vs fishing, bourbon and soccer) brings some newness into the conversation.
