There are a significant number of pro athletes waiting to get poked. I don't think they are waiting because they are selfish. I think their doctors, trainers and other healthcare professionals are telling them they are low risk and might be putting something in their bodies that could hurt them more than help them. I think pro athletes are assessing the risks. I know many of you don't, you think they're stupid or selfish. I think this is a very serious and important decision they are facing and they truly believe they are doing the right thing for themselves, their career, their team and their sport.
