    Description, as the server wrote it
    Estimate blood alcohol concentration in permille (g/kg, the German unit; 0.5 permille = 0.05 % BAC) from body data and drinks, using Widmark with Watson body water, a 10-30 % resorption deficit and 0.1-0.2 permille/h elimination. Returns the peak and current value as a range and conservative hours until below 0.5, 0.3 and 0.0 permille. Drinks: either an id from list_drinks or ml + vol (percent ABV).
