Reading up on the recommendations of the so-called "Spartan Diet" had me musing,
"Oh, please; if you were going to model your diet and fitness upon the regimen of an ancient warrior culture famed for strength, battlefield prowess, self-defense, and personal/familial honor, you'd CLEARLY be better off doing so using the Klingons as your model!"
OK, so Klingon food and drink is largely animal-based and their training protocol is unparalleled, but I must admit that for a human to adapt to that menu (boiling worm wine, durani lizard skins, etc.) would take quite the cast-iron stomach.
If you had to convert your menu and training to those of a fictional culture, which fictional culture would you chose? Bonus points if you link to a wiki or other page explaining the foods and/or training.
