Fig. 1 YOUTH: Archaeologist is bouncy, full of good intentions, working on a prehistoric research dig. Gullible as hell.
Fig. 2 MATURITY: Archaeologist has dreadlocks. Working on an urban site. Smoking banned substances and reading William Shatner style science fiction. Can't understand why members of the opposite sex don't find them alluring.
Fig. 3 OLD AGE: Head shaved bald after bad dose of cooties. Working part time on mushroom farm. Is on first name terms with dole officer. Argues with everything said to them, even compliments.
