from http://www.geocities.com/shankar00/jpjsite.html (in 'Trivia'):
- Does JPJ eat meat?
"I stopped eating meat for a number of reasons - I don't like what they put into it, and raising cattle is not a very productive use of land. Since I've stopped [eating meat], I've felt better." He does eat fish though - "I love fresh tuna, salmon, shellfish, and crab... I'm very keen on Japanese food, especially sushi."
- Then what does JPJ eat while on tour?
"Even when touring, I've always found good places to eat. You can't live on drugs and alcohol alone."
