This gets me (not litterally), we can clone a sheep or dog and apparently a human too (except legally its not allowed) yet we havent been able to figure out a cure for Cancer or even the common cold?!
I personally think someone has, but it is all being kept hush hush. Apparently the worlds population is increasing in size equivilent to a city of Southamptons size every day. With this in mind, if we cured Cancer (1/3 people contract cancer now) so many people would live longer meaning the worlds population would grow even quicker. I think the powers which be maybe holding off the cure for 'the greater good'.
