This is a great book in some respects. It collects many concepts concerning aging and disease. That said; it is a disappointment because the book suffers from poor editing. It is replete with misspellings and grammatical errors. Further, there are sentences that are completely meaningless, as if the author was interrupted in the middle of a thought.

This is a tough read, not because of the subject matter or because of the level of sophistication. It is a tough read because of the errors, and because of the sentence structure. Too bad really, I expected more after reading the review in Science.
