I like the appearance of the site, looks nice.
I'm not real fond of your sales pitch.
"Free Anti Aging News Blog Updates", maybe it's just me, but doesn't "Blog" basically imply News and Updates? Sounds redundant.
Also, since you're selling to an older market, you might keep in mind, many of them will not have a clue what a "Blog" really is. If you don't believe me, ask 10 people over 65 what a blog is, and see how many can tell you.
Why "Just a few facts"? If I were interested I'd want more specifics, more facts, what types of conditions are you going to give me information about. You need to hit them in their individual "pain point" or they probably will never put in that email address.
I'd rather see your page 3 times longer with more information and the signup box shown about 3 times.
Just a humble opinion...
