I seen something on BBC News recently with an expert on Antibiotics saying in 20 years time,the current drugs we currently use will be useless,as the bacteria's are becoming immune.
He also said the major drug companys,ie GlaxoSmithKline need to start work on new drugs for 20 years time.
So called expert probably works for a drug company, great sales pitch! We must protect our multi-billion dollar industry even if it means telling the public porkies.
