Blood group characteristics

Was looking my inbox and I found these cartoons sent by John quite some time ago. Well it was marked as unread, so you can guess that I don't read all my mails, haa. But I think I'm not the worst around, I only have235 mails marked as unread, thats not as bad as alot of people right? Anyway these snipets are talking about the characters of different blood groups. Pretty interesting.
