Why?? Are you the same height, weight and bone structure as Osensei was at the age you have currently reached? Have you ensured that your calorific needs are the same?
For example, are you going to need to wrestle bears (or kill bandits) as you may want to include some supplements to ensure full health during these stressful exercises.
Finally, just WHY????????
Please someone explain this to me as I was not aware of Osensei renowned abilities in the areas of diet and nutrition.
