no book. I am not short. Held and have been buying this company for a few years. I used to own Geron! I have read the MB for years never had the urge to join. Just a lot of junk on this MB that it never interested me to share. But as ACTC seems to get closer to their goal if you will I would like to read and educate myself (lol) if possible from certain individuals opinions and knownledge. I take what I like and leave the rest.
