Anybody who wants to see will see how their statements "OC is safe!!1!11 I'm doing it since months now!" are based on poor knowledge and ignorance, and those who don't want to see are going to do whatever they want to do anyway and are not really interested in the true implications of OC regarding lifespan and reliability. So I suggest you slightly switch topic here to define and debate about definition of "safe" while I follow more promising things than this thread. /j
