Actually, Helmut, there was a study done. At the University of Northern
Nevada: Angst, Gilmore, and Fosdick showed that Malacolgists smoked 2.45
times as many cigars as did butterfly collectors. The A,G,&F study went
on to place other collectors as well, and also concerned their alcohol
consumption.

COLLECTOR        CIGARS INDEX    ALCOHOL INDEX
Stamps                  1.7             2.63
Coins                   2.87            2.1
Shells                  2.45            4.8
Butterflies             1.97            1.65
Antiques                3.41            3.56
        I do hope this helps.
