You can ask about and try out different jobs to get a bit of insight and more data points for making a decision. Even if you won’t have a definite favorite you may find things you consider undesired or desirable for you.
How little food intake is enough to sustain extensive (physical) activity.
The little birds running on the beach with every wave, eating mini things. How can those be enough to sustain that much running? And it’ll have to sustain them when they’re not eating too.
A human can not eat for several days and still stay active. An incredible adaptation. I food conversion, storage, and priority dissolution in a complex system.
This makes no sense to me. It's just generic platitudes and a wild claim.
You say "quite the contrary", claiming there is scientific evidence of consciousness having nothing to do with our brains. Where can I find this evidence?
I couldn't follow any of your reasoning. Can you summarize your central thesis? Because we observe...?
I don't see how conscience could not have anything to do with our brain when that is where it arises.
