When I have people to stay I dig out my old filter coffee machine, the kind with a water tank and a glass jug. I have a couple of cafetieres, but rarely use them; some of my visitors prefer them.
Our parents used to make ginger beer when I was a kid. There was a "starter", some kind of yeast? Then a raisin or two in each bottle, and of course ginger. Every now and then you'd hear one of the bottles explode. The surviving bottles were delicious, effervescent and spicy, not too sweet.
My brother in law recently acquired one of these and is obsessed with stalking and blasting flies with it. He shot a big blowfly and it exploded in a ghastly mess on the wall. Very effective and - according to him - satisfying.
I cut my own hair during lockdown. I did it outdoors, using regular scissors and a mirror. It came out not too bad, from the front anyway. Not sure what the back looked like - it felt ok. That's shortish hair, I'm sure long hair would be easier.
When I lived in Edinburgh's Old Town in the 90s I had a couple of young guisers come to the door, not trick or treating, but "a penny for the guy"*. I gave them a pound each, they were thrilled.
*The guy is Guy Fawkes, "remember remember the fifth of November".
I do a lot of water sports in the UK and we use VHF radios. Certain frequencies are used by marinas and the like, and nearby boats will be tuned into them. Then there is a frequency used for emergency calls - the coastguard listens on that and answers, and will move your call to another frequency for more details, leaving the mayday one open again.
We mainly use VHF for boat-to-boat comms, or boat-to-shore. The local range is decent - a few miles from our base, depending on atmospheric conditions, obstacles etc. I honestly have no idea if you could use VHF radios between cars though. It's not private for a start - everyone can hear you - and once someone is yammering on the marina frequency no-one else can transmit. So it's just brief messages with protocols.
My friends and neighbours and I all use a variety of messaging services and apps like Spond to organise get-togethers, sporting events, working bees etc etc. I'm in a ridiculous number of WhatsApp groups, all very active, and I see most people in them irl regularly. Without the internet I don't know how we'd cope. It's hard enough herding cats in a group chat, imagine the number of phone calls we'd be making!
I hate the SMS ones, because I don't have a good phone signal in my home, so I have to ruin around trying to get a couple of bars so I can get the effing code. My banking app just uses a fingerprint.
Swimming works for me. I joined a gym at a hotel that has a pool, reasonable price and usually fairly few people. I like to swim lengths, thinking of nothing at all, for half an hour to an hour. Good for general fitness, stamina.
I have a ceramic filter holder that sits on a mug. It uses two-cup paper filters, which I compost after use. https://algeriancoffeestores.com/products/ceramic-filter-cone
