I don't disagree with all the good it could do, but the scale and type of danger it has the potential to cause unfortunately leads me to not want it to happen. Everything has a price and at some point someone involved with the set-up will get bought and an accident would leave the information in the wrong hands. I certainly wouldn't want other bits of me grown by scientists - people would be stitched up for crimes left right and centre.
It seems to me that the second you put people's own unique DNA on a database, it is no longer unique..........
