In many ads about germicides, it is claimed that so and so soap kills 99.9% bacteria. This means that if there were 100000 of these microscopic beings, after treatment 99900 will be killed but still 100 will stay alive. One thing they don’t tell is that bacteria growth is exponential and within no time they will multiply again.  As the number of surviving bacteria will be less and amount of food is same as before, their proliferation rate is very high and they will grow within no time to large numbers. Only limiting factor against their growth is the starvation when the food is exhausted. Don’t be fooled that they die when the food is exhausted. No, they become dormant and wait for the food to become available again and again they revive.

The fact is we are born with “conditions apply’ tags and we are bound to play host to millions of bacteria who live inside and outer skin of our bodies. Many of these are beneficial to us.

What the bacteria lack is size they amply make up in sheer numbers.They live everywhere and there is no escape from them except immunity levels which are different from person to person and also with age.

Lack of knowledge of general people is used by the manufactures to fool them.
