I'm 86 years old and spent my whole life in a farm where all the vegetables and meat have mostly come from this land, I feel very fortunate when my grandkids are around and wake up to birds singing.

My husband’s grandmother is turning 109 this May. She doesn’t have dementia and her mind is still sharp,but her body has become very frail. She had four children, and her oldest passed away last year at the age of 84. It was very hard for her. She once said that living so long isn’t always a blessing, because you end up watching the people you love pass away before you.

I know very few people will understand this. But I’ve always felt like I was gonna live forever. Let’s just say things that I’ve always thought what happened to me has happened.
@River_of_change_
Over 10 years, I've progressively given up:
- Alcohol
- Junk food
- Toxic relationships
- Excessive sex
- Excessive coffee
- Anger
- Grudges
But I've been stuck for 3 years now with:
- Judgment
- Irritation
- Vanity
- Pride
Especially, quitting toxic news has been tough, although I've managed to reduce their consumption.
Even this was enough to radically improve the quality of life.

I am 55, after my parents divorced in the 70's we moved to a derelict home in the country without running water. It did however a functioning well and was surrounded by fruit trees and a walnut tree. Eventhough we had hard times, I wouldn't trade those tough times for anything! The well water was sweet and cold, we climbed trees and ate fruit from the trees and were never ill. One of my sisters has moved back to the country and started a farm. I am now focused on what I am putting in my body, cooking at home, walking more and trying to do what I can do to age gracefully.

I am 70 my partner is 46. At times he seems to be the older one. I have always been an optimist. I now realise a positive frequency/chemistry helps keep me youthful. I had a perfect day when I was 16. I came home laying on my bed, looked at my grass green feet and inprinted the sensation of my body/mind. I was healthy and happy. I still go back and imagine myself in that state of youthful joy. I always feel great afterwards. ❤🌞

I was very attached to my grandmother, this is how I saw her – like she was a cool young person stuck in an old body.. I miss her terribly.

I interviewed an 86-year-old grandfather on my podcast about the secrets of longevity. He mentioned to me: thinking, quality water, simple nutrition and returning to nature. He looks at least 10 years younger and is an example to all who know him: cheerful, serene and wise.
