Can We Stop The Ageing Process?

No, it is simply not possible to stop the ageing process, all that we can hope to do is to minimse the damage the ageing process will do to us, thereby helping us live longer and to be fitter.
Many supplements and 'miracle pills' are on the market which claim to 'halt' the process or turn you into a twenty year old again, but they cannot really do this.  They may however, boost your body's ability to cope with the ageing process.
Scientists in America in 2002 took out an advert in Scientific American to actually highlight the fact that there was no remedy on sale which 'has been shown to slow, stop or reverse human ageing', so concerned were they that people believed they could stop ageing and were paying money to acquire the latest anti-ageing product.
Ageing is a natural condition.  If we did not 'wear out' the world would not be sustainable, so this situation is unlikely to change : ever.
