Well as long as you understand and do not use double standard (consider something is fact based on what you want believe and something is nonsense based on what you do not want to believe) everything is alright
Faith about what, do God tell you to drink tomato juice, to do sport or eat fruits, to prevent Prostate cancer? where do get that info if not from media or doctor ideas, from that point view you believe and have faith in them also.
Are you doctor or not? if not, you cannot claim that you are knowledgeable than doctor. what the hell you compare bone and masturbation? back to the topic dude. Overloaded sperm become one of the factor for prostate cancer. that why elder usually get that disease, if they do not undergo vasectomy
