5. He's Athletically Built And Gets In Fights
Members of most of the archaeology departments in UK universities read like a who's who of terrible shape and bad sporting records where the hell would the strong frame and high fitness level of Indiana Jones fit in? Nowhere. We also frequently see him in fighting henchmen or Nazis or genuine criminals and at no point does he panic, runaway (whilst crying), or throw down his wallet to pay-off his attackers, which is very likely to be what a real archaeologist would do in that situation. It may interest you know to that professional archaeologists often have large and highly trained teams of armed security accompanying them when they do archaeology stuff in dangerous countries; but no, Indy (the university professor) is too hardcore for that.
