I have known about "rewilding" for years.
I also have a bit of experience on both sides of this topic as I sold my house a few years back, bought a van, and began traveling the USA. I did this AFTER walking the Camino many times, and realizing just how little it takes to make one happy. One thing I loved most about it was the feeling of FREEDOM from those possessions that I realized were weighing me down. Another was the ability to enjoy the wonder of God's creation. I'd move my van every week or two to a different location, and so I had a "different front yard" to wake up to. I slept like a rock, being so close to the earth. I'd wake up before dawn, make my coffee, and watch the beautiful sunrise every morning! At night I'd go to sleep as soon as the sun went down. I walked every day. I watched wildlife. I ate less and healthier because I had no refrigeration. I felt better than I'd felt in years.
I grew up on a farm, and so I spent my childhood days outside. I didn't realize until living in my van how much living in a sticks/bricks house limited my life, my joy, and my health.
Then in December of last year, breast cancer visited me. I spent a few months in my son's house recovering from surgery and was just looking forward to getting back on the road, when my elderly mother took yet another fall and asked me to live with her and help her. Regretting it now, I took the bait. I helped her sell her house, sold my van, pooled my savings with her cash, and bought a house with her, and now I'm feeling "stuck" inside again. Though it was fun (like a birthday party) opening the boxes I had put in storage with things I loved, and handling them all again, I have realized that for me, the freedom and joy of living close to nature far outweighs owning and caring for possessions.
As a sidenote, and this is my own personal opinion, I feel my breast cancer was caused by radiation from my cellphone. I have MCS and am VERY sensitive to electromagnetic energy. This is genetic. My grandmother had a box of about a dozen watches when she died. She'd wear one for about a week, and it would stop and never run again. Street lights turn on when I walk under them. The buzzing of a television remote drives me crazy. It's weird, I know, but true. At one time, I had laptop that required I rest my wrist on when I used it. My wrist would quickly get hot and achy. I had to get rid of it. Now the mouse on the computer hurts my hand. It gets hot and achy, which is why I'm not on here as much. Before I found my cancer, I noticed my left arm was constantly aching and numb. The doctors could find nothing wrong. I hold my phone in my left hand when I use it, and when I was in the van, I used the phone for internetting, which means I was on it a LOT! Now that I'm aware of the issue, I stay offline and off the phone much as possible. I turn my phone off at night and leave it in a different room, I sleep better, and I do my best not to use it for being online. I know some of you will laugh, but I believe what I'm saying is true. I believe the radiation from the phone is dangerous. You can post all the scientific studies you want. I know my body and what it feels. My gut tells me and I believe my gut.
Being out in nature, out in the middle of the desert or forest with no houses around me, going barefoot, breathing clean air, walking, gave me the opportunity not to be distracted by EMFs, television, radio, internet, shopping, and I found more peace of mind.
I'm a fan of rewilding!
Best wishes for your success!
