the human brain is a complex chemical stew

knowing what makes it happy is not impossible or voodoo woo

the older i get the more i get concrete verification that very often these things are as simple as nutrient deficiencies, and toxic reactions to synthetic "foods"

there is also other, higher level things going on but they don't have as substantial effects... if you fix your foundations, often the flappy bits on the roof settle down 

 Good advice 😊
