there have been some developments for lung tissue regeneration through stem cell research.
oh, and i'm a smoker.

fuck that. I saw that shit on discovery channel. They had a big thing on the human body and they went through every organ. They went on about this particular thing for about 15 minutes and it was the part where i payed the most attention to. I saw it twice, just so you know where i got it from. I really dont think they would make that kind of stuff up.
