Precisely....where possible we should allow our own defence system do the job. That way WE get toughened against baddie bacteria and not them getting toughened against us.

We should go more down the road of trying to mimic exactly what it is that our bodies are doing when they enter into a war on baddie bacteria, and stop using so much drugs.

And of course as we see over and over again one of the best sources of self protection we can get comes from a healthy and balanced diet.

The medicos have been warning us about this for years.
Pity we didn't pay attention.
