You want just enough microbiome, and it should all be in the colon.

The microbiome includes your skin mouth stomach and intestines.
Your appendix also holds a bunch of bacteria and stuff that it releases back into your stomach after you've been sick etc. to replenish the internal microbiome
The appendix bit is wild and it's amazing this is so little known.
