Many junkies could talk with surprising poetic eloquence about the joys of internal chemistry. The most fluent and intellectualized junkies were generally the people who were most visibly falling apart. Junkies were just about the only people in the modern world who looked really sick. Junkies had boils and caries and stiff lifeless hair; junky squats had fleas and lice and sometimes that endangered species, the human pubic louse. Junkies had feet that peeled with hot itchy fungus, and noses that ran. Junkies coughed and scratched and had gummy bloodshot eyes. There were millions of people in the world who were elderly and in advanced decline, but only junkies had backslid to a twentieth-century standard of personal hygiene.
