Playing in the sand or messing around in the mud never did a child any harm. Nature is full of good bacteria and it makes good sense to expose our children to it.

- We have 10 tril­lion own body cells but are pop­u­lated by 100 tril­lion bac­te­ria. If we laid them out length­wise they would go all the way around the world.
- Most bac­te­ria are found in the colon.
- It takes around three years for the mi­cro­biota to set­tle into an in­fant’s sys­tem.
- The mi­crobes in our in­tes­tine weigh be­tween 1 and 1.5 kg.
- There are around 400 to 500 dif­fer­ent bac­te­r­ial strains in the in­tes­tine, com­pris­ing 30,000 to 50,000 species.
- Sci­en­tists as­sume that bac­te­ria com­mu­ni­cate with each other.
- Un­for­tu­nately, an­tibi­otics kills the good bac­te­ria as well as the bad.
