I said the same thing in a previous HN discussion and my comment was down voted into oblivion. Many Asian cultures had this thing figured out thousands of years ago. Less or no meat. Many famous martial arts schools (Indian, Chinese and Japanese) are totally vegetarian. So, the argument that meat is needed for extreme physical activity goes out of the window. Almost all Asian monks (Buddhist, Jain or Hindu) are vegetarians. So, the argument that meat is needed for better mental\intellectual health also goes out the window.
