Quote from oldtime:
same reason the KEMO lady puts herself though all that destruction, if you don't actively control depression it can end up in suicde, especially if you make an unmentally balanced trade and go into a bad drawdown. These days, a joint can last three days, so I doubt there is any noticeable physical harm. Life is a bitch if your nurons are firing uneven, and you can either do something about it which gives you a sense of well being, restores your appetite and gives you new interest in sensuality or do nothing about it and endure it because free thinker doesn't like it.
I think there is lots of truth here.
I knew a guy who killed himself after losing 10,000 in the market.
"actively control" is the key point.
