hm... amazing story. although I agree with Athon that it doesn't seem to be strictly factual.

his face "froze" 19 years ago?? faces don't freeze unless they.. well, freeze.

I don't think it could be explained by the botox-analogy.. age is more than getting wrinkles. for his face not to age it would have to regenerate cells at the rate of his youth.. and if that was the case - well there's your fountain of youth.
