finally the first post here that makes any sense. There is a difference between adhering to a vegan diet he being “a vegan.”If you are vegan soley for perceived health benefits, then there's no hypocracy in using natural gut strings.
If you site ethical grounds for being vegan, then using gut strings is totally hypocritical.
and many more people on tour other than djokovic have taken up eating plant based diets. It’s a trend right now for athletes.
