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 grandfather was born in Crete. He lived to be 103. We had authentic Greek food daily. We would walk to the Greek store daily. It was wonderful.

Excellent research... my wife is 47 now, she had her first baby at 45 yrs of age...We got married in 2022 and had our first baby in 2023. She is extremely active, hardworking. All her life she slept for only 6 hours, had stayed without food for 16 to 20 hours. She ate meat everyday, and fish rice everyday as well with lots of veges. She is so wise and matured but her look was like a 25 year old when i married her when she was 44...with no white hair, no wrinkles...and a glass flawless skin like a young girl. Ofcourse she is still young. She has a bubbly optimistic personality and she doesn't believe in any routine and system except sleeping at a fixed time. Everyone said she is too old to have a baby but she was too sure that she will have a baby and her optimism made everything possible. She needed no medical help at all and she even did all household, and did hiking during her pregnancy. I believe having faith and optimism, and keeping the mind young helps the body somehow.
