That's an interesting custom. I'm not so sure I would like raw egg like that.
Before there were so many issues with consuming raw eggs I used to like to eat eggs raw on hot cooked rice with a little soy sauce. The raw egg does cook a bit when you put it on the hot rice and stir it up.
I agree with your opinion @lightsplasher, consuming raw eggs is not good, what else is excessive what else for the less exercise.
