as Citymonk said
"-it is natural for human to eat as mush as he can including fat, meat, and other “unhealthy” staff
-it is natural for human to sleep when he want (not going party or watch VT all night)
-it is natural for homo-sapience to kill another homo-sapience for food, territory, etc (we still do, but on another terms)
-it is natural for a male to be monogamous
-it is natural for human to endure pain without painkillers
-etc, etc, etc"
In the first one, is that natural or is it natural to listen to our bodies. Personally I dont want to feel bloated all day. I dont like to be able to taste certain foods in my mouth all day. If I eat a big thick steak, there is a feeling that happens after that I dont really like, So I have cut down my meat consumption and can see myself living without meat or very sparingly. If there was an abundance of fresh foods easily accessible, how would my eating habits change? Personally I like lemonade with honey and lemons, fresh squeezed, more then I like coca cola. Personally I dont like the taste of “conventional” california oranges, but have had some local oranges that were very good and tasty.
To sleep when one wants, I would have to live with no time restraints from socioty, for a while, to give any type of appropriate response coming from personal experience.
To kill? My natural disposition, since I was a child, is peaceful and as a human being I do not really care for conflict. Other people may be different.
monogomus? well a lot of factors could be in that one. Is the male happy with himself, his partner, or is he looking for something to make him feel whole or alive? is there a healthy sexual relationship between partners? Are the mates opposites that clash a lot, or are they accepting of differences. Are they influenced by cheating people and accept it as normal or no big deal, etc…
From my own experience, when I get sick I dont see the doctor, I will get herbs, fast, and sometimes do breathing exercises. I do have enough references at hand to where I have not been sick longer then a week for as long as I can remmeber. That sickness in particular, the other two people who got it at the same time were sick for three weeks. Beyond that sickness, I have not been sick for longer then three days besides an ear infection that was taken care of holistically as well. This dates back about 16 years.
I did have knee surgery about a month ago and used the anesthesia to go under. That night I had one pain pill and one pill for inflammation after that I stopped taking them. When I saw the doc the next week she said I had one of the best looking knees she had seen all day and that I got an A.
wht is natural for each human being may be different, I dont know this answer. From my experience I do not believe all those things are natural for me. Thats my take on it.
