Around 19-20 maybe. Friends I had in america at that time entertained all kinds of shite, zeitgeist the film was out around then. I always retained enough skepticism to avoid tipping over into full evangelist but all that stuff was enough to darken my day-to-day experience for a while, knocks you off balance so you doubt everything. and daily drug use was absolutely a factor, and is a factor in the people I know who have gone off the edge a bit. It also happened at a time when i had a health scare, which exacerbated everything, a feeling of suspicion in my whole body. One of the things that grounded me again was good info and care that took me through that.
