Thanks for that James. The way they created clones in The 6th Day would explain how you can make a clone of an adult quickly,that is, by having bodies full grown in suspension and then infusing them with the target's DNA and memories. An argument against adult clones would be that they would take too many years to grow but the method in the film would explain this. The only discrepancy may be recent memory inconsistencies so if you ever meet your clone James you can ask them some recent stuff and bamboozle them!
Regarding Africa I heard a recent interview with Zulu shaman Credo Mutwa who said that AIDS is ET technology and the dark powers infected Africa with it to destabilize the country so that they can get their hands on it's apparently massive oil reserves - keep an eye on Zimbabwe I say and possible 'UN peace keeping' intervention...
