Why the 'avoidable' ones? That doesn't even make sense as they are fatal. Wouldn't genetic problems be the one to cull from the population until it is treatable at conception?

Dark thoughts, granted my first thought was to trim the gene-pool. Would give the most immediate and long term affects. Just a bit of a gruesome thought and not something I, given the position, could sign off on. Would have to be some dire straits.
