Scientifically proven, there is no completely healthy person in the world. Bring any first passer-by to the hospital and do a full physical, you will find three or four sores that he might not have known about.
As for psychology, it is somewhat different. If our body has remained unchanged for long hundreds of years, then the moral foundations changed from one era to another. In ancient Rome, gladiators threw off nine-year-old boys and called them heroes. Were they called psychos then? No. Because the "norm" in psychology is a shaky thing. Two hundred years ago, homosexuals were despised all over the world, and now in many developed countries they are recognized and given rights. Before, being homosexual meant you were crazy. You're just gay now.
You can have a healthy psyche, there are billions of such people. I do not consider minor phobias or minor deviations to be serious trauma.
In theory, everyone lives his own way and projects an attitude towards any of the things around him based on personal experience, it's all about the attitude and the assigned meaning (bipal), that is, the lifestyle and addictions of some aboriginal will seem to you to have gone or, let's say, subjected to physical and moral pressure of a person craving for violence and other things.
