I am nearly the worst role model for a healthy person. To me, a healthy person is someone in balance. Sometimes you eat hamburgers, sometimes salad; sometimes you move, sometimes you don't. I eat more healthily than unhealthily, but I do sometimes eat unhealthy food.
What we have done, the result of that comes to us whenever it comes, either today, tomorrow, hundred years later, hundred lives later, whatever, whatever. And so, it's our own karma. That is why that philosophy in every religion: Killing is sin. Killing is sin in every religion.
