Well, a fine job alone doesn't make decency. A few weeks ago we met that guy in a pub; turned out he was an OTA (that's the german term for people assisting physicians during surgergies, preparing the operating room, handing surgical instruments mid-surgery, etc.). He had to be at the hospital at 7:00 in the morning, still celebrated with us until 5:00. :|
But yeah, I know one girl of that kind. She was part of a group I went to a goa with once; told us she had ecstasy the last two nights, still ate four pills at the party. Kind of disturbing. Using MDMA to cover misery is but counterproductive, considering it causes your brain all the more misery. It's one of those drugs barely posing a risk when used wisely and rarely, but completely messing your brain up when used excessively.
