Before I left to California, I was steadily trying to gain weight & I was obsessed with growing your own food. Self-sufficiency. I theorized that the cure to depression was becoming self-sufficient. I learned that a human has to participate in life – a stewardship, a contribution – i learned that digging your hands into the soil raised serotonin in the brain, vibes to feel happy.
The Russian astronaught who holds the record for the longest time spent in space had to grow wheat to keep himself from feeling depressed (which affected his physical body.)It gave him and his crew something to talk about, and it gave him something to care for.
The body and the mind are connected.
