 way that they found out that serotonin was important with depression and mental health disorders is by giving someone something that impacted their serotonin and then being like, hey, that must be a reason. And that's something that I think about a lot because from doing my biomedical sciences course, I know that the way that science is supposed to work is you're supposed to find a target, find a reason, have a mechanism, do trials around that and then produce things that might be able to counter that. Whereas with anti-depressants, it's like the opposite way. It's still not very understood. No, it's really, I mean, I think of that every time we take a medication that most of the time when I read about it, it says we still don't understand the pathway.
