Everyone has his/her pride. And from what I read on this board, It's very important for the male species with Serbian heritage
Nole has been pounded by media all his life for his retirement/wo. His pride took great hit. When he was a small kid and had his career ahead of him and he had no idea what's the problem with his health, he was cautious. He paid a price for that. Now he's a grown man, reached certain level in his career and IMO he has the luxury of taking care of his pride.
Let's hope this injury is not a serious, long term one like DelPo's and leave Nole with his pride.
