For me, working in human services does the trick. Over the summer I take a vacation to heal body/mind, and swap to spending more time on MMOs, a Mud, and making sure I go “out” somewhere at least once a day. Even just to the library.

Live with friends.

• Sport and art
• low cost and free places to do sport and art
• linked together by public transit and clean, safe places to walk, run or cycle (or scoot or skate or whatever)
• a shorter working week, so people have time to do the above
• a higher minimum wage, so people can afford the (ideally low, if necessary) costs involved

So, e.g., lots of parks with publicly accessible five-a-side football pitches, ping-pong tables, basketball courts, skateparks whatever - that's your sport. The parks also have bandstands or outdoor theatres, where there's space for that.

Public libraries with rooms people can hire (or use for free) for book clubs, sewing circles, art classes - that's your art.

Good thing about the above is that all these ideas already exist in lots of forms, you just pick whatever works best for your current situation.

Less pants

Mandatory copulation every 14 hours.

I don't think there is a solution. I think this is the path and these are the results.

Is the epidemic one of loneliness or one of improper socialization, a background fear of people and purposelessness? Sadly, idk how to make people change their minds and hearts besides just talking to them and hoping something sticks.

Capitalism is a root cause. Let's get rid of that, or if that's too extreme that severely regulate it.

Jail all of Facebook's decision makers. Seize it (investors get nothing), and either shut it down or revert it to a simple message board. Require moderators. Ban the trash (eg: sovereign citizens groups). Remember that time they tried to see if they could make people sad by changing the algorithm? Find those people and ruin them.

Pay labor more. Work them less. I'd just do basic income, personally.

Make more walkable spaces. Fuck car culture. You don't meet anyone when you drive. Everywhere could have local spots where you see regulars.

More free public events. Brooklyn does "movies under the stars". There's also like yoga classes, bird watching, concerts. More of that.

Offer free education for anyone who applies in good faith. Offer classes on a range of subjects, but honestly I think a lot of people would benefit from lessons and practice on "how to talk to people" and public speaking.

Kind of a ramble. But I think if you leave capitalism in place, you're going to have problems. "Everything has to make the owners as much money as possible, immediately" isn't a formula for a good life.

Plenty of good real solutions in the comments here. My creative solution is to add a feature to everyone's phone that automatically will FaceTime them with someone also on their phone in the area. You can't turn it off, you can only add people to your default list. No guarantee they're who you connect to though.

Try and find where my invisible friend went then hang out with them again.
