WebMD aptly illustrates the problems facing newcomers to the field of healthy life extension: faced with the noise generated by the anti-aging marketplace, how do you find out which claims are legitimate and which of the legitimate claims are useful? How can you distinguish reputable scientists and doctors from the quacks and adventurous marketeers? It took me several years of being a customer and advocate to sort it all out in my own mind - it certainly isn't as easy as counting red flags, but that can help you avoid the worst traps. Be skeptical, do your research, and remember that there are no simple solutions. Hopefully the materials at the Longevity Meme will give you a head start on the process.
