Scientific integrity and advertising on my sites

It has been pointed out to me that this Blog and my Anti-Aging Firewalls treatise sites are now experiencing enough Internet traffic that I could generate revenue by accepting advertisements such as for proprietary dietary supplements, health cures, anti-aging treatments, anti-wrinkle creams, etc.  While the money would be nice, I will continue to follow a non-commercial model such as that of a professional scientific journal.  There are several reasons for this.  First of all, many advertisements seen on other longevity-related sites make me uncomfortable.  They claim anti-aging results based on science that is shaky at best or nonexistent at worst.  They go against the messages I am trying to deliver.  Services that automatically place advertisements on my site would not give me the option of filtering these out.  Second, I don’t like the idea that any one substance or approach is the central key to longevity today based on the state of science as it is.  And third, I want it to be crystal clear to my readers that my commitment is to the science of longevity and that I will not beholden to any commercial interest.  I think many longevity-related articles appearing on commercial sites are very good.  But I am in this game for the long run and do not want to go in a commercial direction at this point.  So, no advertising.
