Volunteer your time!! So many non-profits need regular support. It's the best way to make a difference for everyone (including yourself).

Tantric sex?

A streamline talk show host. You gather well. people's interests here.

Ballet. I took it up when I was 48 and have loved it. It ties in well with yoga and the intricacy of the moves is apparently good for your brain. And as I can attest, you do not have to be good at it to enjoy it.

Gardening or aquaria?

Learn to ride a motorbike. I don't know about over there, but here in the UK there is a great social scene around bikes. Women are welcomed and treated as equals.

Bladesmithing!

I am projecting, sorry.

Bake Cookies! All kinds of cookies. Too many cookies. Give them away. Everybody loves a good cookie.

Frog chucking is purty fun...sorry, feeling awnry. Maybe donating some time at animal welfare or community help programs.

SCUBA Diving! Super awesome, and a great excuse travel and vacation in warm climates.

You can always sell cruises part time and pick up a few dollars doing it.

Build your own electric motorcycles and/or cars?

I know Kendra Horn who is running for Congress in Oklahoma. She used to be my yoga teacher years ago in Boulder, CO. Help get women elected in Oklahoma!

Are you into trivia? I used to be on killer teams out in pubs. You can win tickets to your favorite sports team and lots of mugs.

How about photography? You could post some of your work on the site.

How about public speaking? There is a good group called "Toastmasters". It helps people do public speaking. Although, I don't know of many places in your state to talk about the things you want to talk about.

I could be repeating something. Tai Chi, knitting, Bird/any animal in nature Watching, Volunteering at a local homeless shelter or soup kitchen, writing and reading your writing at an Artists Open Mic, plotting trails to hike across the country, plot out microbreweries to hit up across the country, plan a cycling trip along a scenic route for a week or two and ride it, ballroom dancing... these are just a few of the things i personally do, have done and/or am devoted to. My next big goal: I want to learn how to pilot a plane. I am intending to begin this coming spring/summer. There are just soo many things I would like to learn to do in this lifetime and sooo little time! haha

Pedal a bicycle for both exercise and the observing of nature.

Getting outdoors to identify the flora in your area.

Once lived in northern Montana way out in the sticks. We did not even have a phone booth so we could go wait for a call. Spent time outside looking up, at the clouds, stars, looking for antelope, which were rare. Sure liked to watch them run. Wildlife is great to watch. Have spent fun time learning to photograph flying birds. Hard to get them in focus, but it is possible. Don't know much about Oklahoma except that movies show there to be tornado's, I will not be moving there. Don't mind a little wind, but something that can rearrange your life, no thanks.

Dancing the tango, keeps you fit and is endlessly rewarding as you explore all its possibilities.

Well, what have you already tried? I like to do jigsaw puzzles, macrame, colour, sometimes do surveys (generally the type of thing that people would post in their facebook notes so long ago xD) and research topics I'm interested in and write down basically everything I can about it longhand and all organizationally and stuff (I really like that for some reason - organizing info together...think it's partly why I so greatly enjoy worldbuilding for my writing/books). What about various physical things like skiing/snowboarding, swimming, climbing, hiking, parkour...? Definitely agree with some type of martial arts. Bird watching or collecting things...or daredevil-ish stuff like skydiving, hangliding, ziplining and bungeejumping. Hmm...boating, biking and off-roading and things like it that I can't come up with the names for right now? Meditation? What about more sports-type stuff like golf or soccer or basketball? Painting, photography, nature journaling, gardening, cooking, dancing.

Sauntering through the woods in search of edible and medical plants and mushrooms.
Lol, that's what I love!
