Sounds almost idyllic until one begins examining health records and vital statistics.
It IS idyllic. And my own experience would cause me to reject the assembled health records. I was raised on real milk, real butter, local honey, garden grown veggies, and wild game, or home raised and butchered farm animals.
It wasn't until I started relying upon "the system" that I was ever ill enough to require a hospital... And a good portion of my recovery can be attributed to a return to the habits of my yoot (the Grace of God notwithstanding).
If you are a statistician, you must realize that statistics (which your records inevitably become) can be bent to say nearly anything. Far better to rely upon the testimony of those living the life (subjective though it be).
