No, I am not, but someone explicitly asked you for an alternative. But it's nice to have an alternative ready, otherwise you just sound bitter. Plus, you are not adding to the discussion, the reader is stuck with the same original question - where do you find contract work?
They asked me for an alternative, and I'm giving low value comments by saying I don't have one?
Not all comments need to add to the original discussion. Saying I do not suggest someone uses Upwork and giving my first hand experience of using the platform adds some value to someone.
Also, the people designing these things have years of experience and are most likely thinking about these designs daily through out the years. So, in reality it's 100s of years of synthesized experience to be able to design something over a weekend.
Seratonin is produced in multiple places in the body (not just the brain, and apparently, most of the seratonin in your body is not produced in the brain), but doesn't appear to cross the blood-brain barrier.
I'm not a doctor but I think what that means is "seratonin in your gut probably doesn't make it's way to the brain; but, the rest of the body is already awash in seratonin, so additional production in the gut can help increase those levels, which may have some sort of yet-to-be-understood action that has an impact on depression"
There is no serotonin in pills. SSRI stands for selective serotonin reuptake inhibitor. It is a chemical that modifies how certain cells reabsorb serotonin.
