How unfair is that on the part of nature?

Man Woman.

You are a man or a woman in life, but you can't choose it at all (at least biologically, naturally). Not only the sexual, but also in general, women are also simply different than men, many more men gamble Playstation or PC, men are usually physically stronger and and and. In addition one has no influence on the own appearance, on body size.

It's wonderful that we all look different.

How boring it would be if everyone was the same.

Imagine that all people are the same and would look and be like Torsten, whom I do not like at all.

Life is a gift, nature is cruel it does not ask whether it's good or bad. So there are not only "injustices" in humans but also in the plant and animal kingdom. To what "achievements" since nature is capable, is remarkable. However, just as there's life, there's also death, that's how it is.

Even the soul has a gender, before incarnation. The sex of the soul results from the type of activities the soul has chosen for, and it determines which biological body is suitable for the incarnation. In this respect one chooses quite his gender.

Unless you can't decide, then that can change too.
