To the best of your knowledge, do you have any bacteria that live in your mouth/digestive system like humans and other animals, or do the immune/regenerative properties that render you virtually immortal also make you inhospitable to any other kind of life?

Ah…

Now we come to the good questions, because someone has been paying attention.

I do. I think I just have a terribly good immune system and so do not get harmful infections. One reason I’ve come to think we are much, much older than your species. Good immune systems and the ability to repel everything (recall that immunity is due to inoculation and successive generations of selected strength against illness) is a mark of evolution. Humans are five minutes old, and hence have not put together the sort of immune system hat can repel most things and yet not harm the others. I believe my species has.
